Hello dear readers. Today I will touch on the error in which at the beginning download windows an inscription appears

This error is due to an incorrect connection. hard drive. Therefore, based on this, I will tell you how to connect correctly HDD SATA/IDE.

Proper hard drive connection.

The most common interfaces of modern hard drives are SATA, and for a slightly outdated interface IDE. SATA is faster than IDE.

This is what IDE connectors look like...

Two devices can be connected to each IDE controller. It can be an HDD and a CD/DVD drive, or two HDDs, or two CD/DVD drives. Typically, controllers are referred to as IDE0 and IDE1.
When connecting two drives, you need to assign priorities to them. In other words, you need to specify the main disk - master and the slave disk - slave to the system. ( sometimes they are referred to as device 0 - master and device 1 - slave). How are these priorities assigned? With the help of a jumper, jumper (in English jumper).

On the sticker HDD drive as a rule, manufacturers indicate how to put a jumper in order for the disk to become master or slave.
Devices connected to these connectors via an IDE cable. Loops are 40 pin and 80 pin. According to the connection mode, the loops are also Y-shaped. They operate in cable select mode. There are three connectors on such cables - two at the end of the cable ( first master, second slave) and one in the middle. The center connector is connected to system board, and the extreme connectors to the devices.

At the same time, the extreme connectors automatically assign priority to one device master, and another slave.
The operating system is installed on the main drive. If the disk on which the OS is installed is connected to the slave connector, then the OS will not be loaded.

SATA interface

SATA connectors on the motherboard look like this.

Devices are connected to the SATA connector using a cord with plugs. The plugs have special "keys", guides, in the form of the letter "G" that do not allow them to be connected incorrectly. Only one device can be connected to one SATA connector, unlike IDE. Connectors are designated as SATA0 - the first, SATA1 - the second, SATA2 - the third, etc. This is how SATA prioritizes hard drives. In the BIOS, each connector can be manually set a priority. To do this, go to the Boot Sequence section or boot device priority. This may be needed in cases where the automatic priority is not set correctly.
Now let's move on to solving the problem with the error no ide master h.d.d. detected press f1 to resume.

Error: no ide master h.d.d detected: press f1 to resume

This error appears when wrong connection HDD. This error indicates that there is no HDD connected to the master slot in the system. This means that the HDD is operating in SLAVE mode, i.e. connected to the SLAVE connector. It is necessary that at least one HDD work in the mode master- main. This problem is solved by simply switching the HDD to the adjacent SATA connector, or if you have an ATA cable, by simply moving the jumper to the master. That's all, perhaps.

Before rearranging any jumpers, shut down the operating system, turn off the power of the computer, remove the cable and power cable from the hard drive, after remembering their positions, and then remove the drive itself (without this, you will not see the sticker located on it).

Check out the pictures on the sticker. If you have a hard drive with an IDE interface, this sticker usually shows three jumper layouts: for "Master", "Slave" and "Cable select" modes. Sometimes there is a fourth drawing showing jumpers in order to artificially reduce the volume of the drive to 32 gigabytes (this may be necessary to work with old motherboards). In the operating room Linux system this mode is usually not required even when using such boards, since this operating system works with hard drives directly.

themselves jumpers find on the same side wall as the connectors. You can determine where the field for installing the jumpers is at the top using the landmarks, which are usually also shown in the figure. Such a landmark can be, for example, a missing output.

themselves jumpers move with miniature pliers. Sometimes one drive configuration option requires fewer jumpers than another. So if you have extra jumpers, save them as you may need to revert them later.

In very rare cases, a sticker with an illustration on the drive is missing. If you find yourself in this situation, report the model of the drive to where repair specialists communicate hard drives. Ask them to give you a diagram of the location of the jumpers on the drive of this model.

When two devices are located on the same loop (it does not matter, hard discs or optical drives), you should either select the "Master" mode on one of them, and "Slave" on the other, or select the "Cable select" mode on both.

Drives with SATA interface do not have "Master" and "Slave" modes. Their jumpers are designed for other purposes. Most common jumpers to reduce the data exchange rate from 3 to 1.5 gigabits per second. They are designed to make the hard drive compatible with older motherboards. Sometimes there are jumpers that control the power saving mode. Their purpose is almost always indicated on the drive label.

After changing the position of the jumpers, install the drive board-side down, secure it, and then connect the cables in the same way as they were connected before. Turn on the computer and make sure all drives are working.

  • jumper assignment

Jumpers, otherwise called jumpers, are used to store information of several bits when it is inconvenient to use ROM for this. The specified information is stored until it is changed, and its modification is carried out mechanically.

Instruction

Regardless of which device you are going to swap jumpers in, be sure to de-energize it. Even if you do not spoil anything by rearranging them while the device is turned on, the change will not take effect until the restart, since the jumpers state is read at the moment the device is turned on.

Use tweezers or small pliers as a tool to reposition the jumpers. In the event that one of the jumpers becomes unnecessary after removal, put it in a container with a lid in case it is needed elsewhere. If, on the contrary, you need more jumpers than it was originally, remove the additional jumper from some faulty device: motherboard, hard drive, optical drive, etc.

If you want to select a mode work hard drive (Master, Slave, Cable select), look at the sticker with the table on the drive case. It shows the options for the location of the jumpers for all three cases. On an optical drive, the mode is selected more simply: it is enough to rearrange just one jumper, and its positions corresponding to one of the three modes are indicated directly on the case. For two devices located on the same loop, it is possible the following options mode combinations: - the first device - Master, the second - Slave; - the first device - Slave, the second - Master; - both devices - Cable select. All other options will lead to the inoperability of both devices.

Floppy drives latest models there are no jumpers at all. If you come across a drive of an older design, set the only jumper on it to the position corresponding to the “B:” device. If you have two drives on the same cable, configure both devices the same way. Which of them will become the “A:” drive, and which one will become the “B:” drive, depends on their relative position (before or after twisting on the cable). Straight cable drives without twists can only be found in computers that are not compatible with the IBM PC, they should be configured with jumpers one drive as "A:" and the other as "B:".

On a modern motherboard, you can find only one jumper - erasing CMOS. If it is necessary to carry out this operation, remove the jumper from the contacts corresponding to normal operation, move it to another pair of contacts intended for erasing, hold it there for about twenty seconds, then move it into place. The location of both pairs of contacts is indicated in the instructions for the board. If there is no appropriate jumper, do not under any circumstances erase the CMOS by shorting the battery. Remove the battery, close the contacts on the board intended for its connection, remove the jumper from these contacts, and only then install the battery in place.

Let's talk today about jumpers on your hard drive. More precisely, we will talk about what these jumpers affect.

It's no secret that the hard drives have a small jumper, which is located near the connection cable. What does this jumper affect and in what position is it correct to install it? One has only to make a reservation at the beginning that the article will not be complete on this topic. There are several types of hard drives, different ways connections and different form factors, in which the jumpers differ and are completely absent there. Today we will talk about old hard drives, IDE connection options.

A jumper on the hard drive is needed to organize the correct launch of several hard drives. Imagine a situation where you have two hard drives installed in your system. It is necessary to determine which of them is the main one, from which the operating system is launched, and which secondary one is loaded as additional disk space.

There are two basic jumper settings. The first one is called Master and the second one is called Slave. There are also slightly different from these two, but we will not clutter up the article, we will pay attention only to the very basics of this issue.

In Master mode, you must put a jumper on the main hard drive from which the operating system will be loaded. In Slave mode, install a secondary hard drive. At startup, the system reads this information and sends a signal further, so that in the end you have the necessary hard drive loaded as the main and second hard disk as a secondary.

Which mode corresponds to which, you need to look at the stickers, which is located near the jumper. Usually the manufacturer specifies the desired jumper positions.

The jumper itself is a small chip, by setting which you close the contacts of your hard drive properly. It is on how you close these contacts that the startup sequence of your hard drives will depend.

Do not forget that the startup sequence of your devices, be it hard drives or a drive, must also be configured in the BIOS of your motherboard. The setup option is more about the constant use of two or more hard drives. If you need to install a second hard drive in order to copy information, you just need to play around with the jumpers.

When the computer boots up, press the Delete or F2 key and go to the BIOS section called Boot. There, put all the devices in the sequence you need.

For example, the first is the hard drive on which the operating system is installed, the second is the secondary hard drive, and the third is the drive.

1st Boot Device - the first boot device[xxx Drive] - the device specified in this line will be the first from which the BIOS will try to boot operating system.

2nd Boot Device - the second boot device [xxx Drive] - the device specified in this line will be the second one from which the BIOS will try to boot the operating system.

3rd Boot Device - the third boot device [xxx Drive].

If you are installing a new operating Windows systems, then you need to set the drive as the first item in order for the Windows installer to boot.

Thus, today we learned something about jumpers and about the boot sequence of devices. If the article was useful to you, then come again. because our database of articles is updated every day!

In this note, I will write how to reset (clear) the BIOS. The article is intended for beginners.

So, for some reason, we need to reset (clear) the BIOS. Or, as they sometimes say, make "clear cmos" (clear_cmos).

To facilitate this action, some high-end and mid-range motherboards are provided by the manufacturer with buttons that allow you to clear CMOS data almost instantly.

They are usually labeled "clr_cmos" (clear_cmos).

They can be located on the front of the board itself:

So behind the motherboard can be located:

And sometimes even without an inscription:

[Instructions on how to use this "quick reset button" to clear the BIOS will be at the end of the note].

But on ordinary motherboards (of which ~ 99% of total number) there are no such "amenities". But there is no reason to be upset - absolutely every motherboard has a three-pin connector. This connector is just designed to clear the BIOS (CMOS).

They might look like this:

As you can see in all three pictures, a two-pin jumper (or jumper) is installed on the three-pin connector. The jumper can close only two of the three contacts. For all motherboards (and hards, by the way), these jumpers are absolutely standard - identical, that is.

This is what the jumper looks like:

They can be found both on the motherboard itself - in the box, or on the motherboard itself, where it is already installed on the three-pin connector in position 1-2 (as you can see in the three photos above). Like in the picture below:

Or find a jumper on the hard drives, where it is already set to some position.

But - on modern motherboards manufacturers usually do not put any jumpers. Then you need to look for them in the store where you bought the motherboard - ask for one thing - and they will give it to you for free.

In this particular case, we will consider the MSI P67A-C43 motherboard.

She looks like this:

On modern boards, the three-pin connector for clearing the kmos is labeled "JBAT1" (presumably - Jumper Battery 1). Looking for her:

Found her. What need to do?

The instruction is as follows:

1. Turn off the computer in advance.

2. Switch the button on the power supply unit (PSU) to position "0".

3. Pull out the 3-pin plug of the power cord from the "ass" of the PSU.

4. Wait then for about 15 seconds and then take the jumper and bridge pins 2-3. Photo below:

If the jumper is already in position 1-2, then the jumper should be moved from position 1-2 to position 2-3. Photo below:

5. Wait seconds 5. Then we return the jumper back to its original position 1-2. Even if there was no jumper, let it remain in position 1-2 anyway.

This is normal as position 1-2 for the jumper is standard/nominal working.

Never leave the jumper in position 2-3! This is fraught with unpleasant consequences for the performance of the motherboard!

6. After setting the jumper in position 1-2, you can turn on the computer. Bios as they say "virginally pure".

P.S. Now about how to reset the BIOS using the "quick button".

We perform the same actions as above, but instead of "dancing with jumpers" we simply press the button.

Jumpers on hard drives (jumpers) show the computer which of the two devices on the "channel" (controller) is the main one - the master ("Master"). And, what, of the second plan - the slave, obeys (“Slave”). Or rather, with their help, the purpose of the disks is established: the one on which the operating system is located is “Master”, and additional disk- Slave.

That is, for the correct loading and functioning of the system, you must first configure the disks. This can be done using a jumper. If you want to install the operating system on new disk- move the jumper to the "Master" position. Then, on the existing "old" disk, the jumper should be in the "Slave" position. If, mounted drive acts as the main one - on the new hard drive, the jumper must be in the “Slave” option.


Thanks to the jumper, the system "realizes" from which disk the request is coming.
Such jumpers are necessary, mainly in relation to hard drives that supports IDE mode.

Physically, a jumper is a small slider made of metal and covered with plastic. In the figure above, the jumper is shown in the red rectangle.

It connects two metal contacts.

Provides the passage of electricity between them.

The necessary information about the contacts is usually presented directly on the surface of the hard drive. Pictured above is the sticker on the disc. It describes possible actions with a jumper - "Options jumper block".

According to the text, when a pair of disks is present, position No. 1 (Master of Single drive) - the jumper on the leftmost contacts - the master device.

In the next position "Drive is Slave" - ​​a disk with two devices connected is a slave.
Position number 3 - "Connection mode of the master with a device without identification", everything is clear.
Position No. 4 - the operation of the device is determined by a special cable.
In the fifth case, the existing system recognizes only the volume of this disk.
In practice, the first pair of options is interesting.

Jumpers, or places where to install them, also have SATA drives. But, there is no need to define "Master" ("Slave"). Enough HDD with motherboard and connect the power supply with cables. The need for a jumper can be extremely rare.

For SATA-II, the jumper is in the closed state; in this position, the speed of the device operation is reduced to SATA150. Instead of a possible SATA300. Used when needed backward compatibility with some SATA controllers (for example, those built into VIA chipsets). Such a limitation does not really have any effect on the operation of the device. The user does not notice them.

Now you know what the jumpers on the hard drive are for.
