Motherboard, Mainboard and Microprocessor Information

During POST (Power On Self Test), the BIOS try to get information about all the devises
Connected to the system. After checking the processor and RAM it checks for devise such you're hard disk, CD-ROM, etc., and display them on screen with messages such
As 'detecting IDE drives.' and Found Primary Master..'etc. Sometimes your BIOS
Just refuses to recognize your hard disk, basically making it useless-there's no way windows will recognize your hard disk if the BIOS doesn't. Let's see why this happens:

Microprocessor Design The most common reason is a loose or badly connected data cable. Make sure the data cable is plugged in properly, both into the hard disk, as well as the motherboard. The same goes for power cable, so check that as well. Also, make sure that the red lines on the data cable and power cable are adjacent to each other.

On startup, Linux uses a small program, usually one called LILO (for Linux Loader), to get everything going. LILO works through your computer's BIOS. Until just a couple of years ago, based computers couldn't recognize hard disks larger than 1, 024 cylinders, which works out to about 6 Gb. Of course, once the operating system was booted up and running, it could support much larger hard disks, but the BIOS couldn't. You didn't need to put all of Linux in that first 6 Gb, just LILO.

Intel Motherboard One you've ruled out any cable problems, check the jumper setting on the drives. If two drives are connected to a port, make sure one is set as master and the other as Slave, or else both are set to Cable Select.

I need to upgrade my BIOS to run some new hardware. Very carefully. The BIOS ( Output System) only memory (ROM) chip on your motherboard. The BIOS controls all your computer's most basic interactions between hardware and software. All modern computers have the BIOS written in reprogrammable ROM, such as Flash ROM or (less commonly) EEPROM. Computer makers provide updated versions of the BIOS so users can download them as they are needed.

Go to the BIOS setup, and under the Integrated Peripherals menu, make sure that 'On Board HDC' is enabled for both Primary and Secondary channels. Also ensure that all drive types are set to AUTO under the Standard CMOS Setting. If you are not comfortable with changing the BIOS values, just reset the BIOS to factory defaults.

If the computer beeps more than once it's trying to tell you what's wrong. Each BIOS vendor (such as AMI and VIA) has their own "Beep Codes", but here are some common examples of what the codes mean. For example a long, continuous beep usually means a stuck key on the keyboard or a problem with the system's motherboard. Check your computer's manual or look on the BIOS company's web site for a chart of what the beeps mean.

History Of Microprocessor When all else fails, so has your hard disk send it to a technician for servicing.

Quite often problems arise with hard disk drives that cannot be solved without a technically advanced disk editor. back up, copying, or recovery of boot sectors and other important data areas of a hard drive; or extraction of information that was removed by accident or lost due to failures, or through the destruction from an erroneous computer virus. For these and a host of other problems, the Acronis Disk Editor software solves and repairs issues associated with hard disk drives.

Acronis Migrate Easy 7.0 works properly with hard disk drives of any size. However, the safe version of bootable media works only with hard disk drives that are properly recognized by the BIOS of your computer.
