Lost power during bios update

Do you have a floppy drive in this PC? From what I've found you you *may* be able to fix it, but it will more than likely require a floppy drive and a disk. Also, you would need another computer to be able to get the files prepared for the floppy disk, and that computer also would need a floppy drive.

In a nutshell, you would use the 2nd PC to make yourself a boot disk, then put the boot disk in the broke PC and turn it on. In theory, if all goes will, it will read the disk and restore the BIOS.
But you may have to change some files on the disk so it will boot to the BIOS recovery program.

If you do have a floppy drive in the dead PC, turn it on and see if the floppy drive light comes on at all. If it does, then the computer is trying to access the floppy drive, which may allow it to read a disk. You will stand a better chance of getting any recovery to work.

With power and no BIOS, you have a doorstop. You can reflash your BIOS with a boot disk but, if your EEPROM is toast, you will have to replace it with a new one. Not a job for the timid.

Seems to be a bad driver or damaged boot.
If the computer shuts down and restarts check CPU fan and blow dust out from heat sink, CPU may be overheating.
Otherwise, use the recovery disk to repair, or the installation CD and do the system repair. Or from repair disk, if your computer worked fine before, Restore To a Previous setting.

The BIOS information is typically found at or near the top of the POST screen for a very short time ALR PC non / PCI = CTRL+ALT+ESC AMD advanced micro devices=BIOS = DEL Award BIOS = DEL Dtk Datatech Enterprises Co.

If the cd rom is not being detected ?

Click start control panel administration tools computer management device manager scroll down cd-dvd rom drives you might see a yellow question /exclamation mark ? ! or a red X right click to update driver You might have to physically unplug the leads for this cd/dvd computer then plug them back in restart your this should activate the found new hardware wizard. If this does not fix the problem it might be a registry problem "you only need to do the following" if you cant see your disk drive in windows explorer Close all open programs Click on Start, Run, and type regedit and press Enter Click on the plus signs (+) next to the following folders HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Class {4D36E965-E325-11CE-BFC1-08002BE10318} This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column. Upper Filters Lower Filters Upper Filters.bak Lower Filters.bak If any of the above keys shown in step 4 are listed, right-click on them and choose Delete

After deleting the keys, close the registry editor
Reboot your computer
Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone.

Some BIOS use other keys like the ESC key. It should be noted on the screen during boot. Plus some have an adhoc boot one time boot menu.

You could also make sure the CD is bootable on another pc.

if you are referring to the installaion disk

restart your computer during the boot process you will see on the screen to press a certain key to enter setup
Press and hold that key during the boot up process to enter BIOS the using arrow keys scroll down to advanced bios features press enter change your first boot device to cd press escape then press f10 to save to cmos to restart

note this will erase you operating system you will have to have an operating system disk to load it onto you hard drive or create a partition to load another operating system
(note after you have loaded the operating system you should go back and change the first boot device to your failsafe or optimized defaults)
after windows has loaded

your computer will automatically restart it might restart 2 times one to finish the installation
the next will be because the operating system is loaded and will boot from your cd
during the boot process you will see on the screen to press a certain key to enter setup
Press and hold that key during the boot up process to enter BIOS using the arrow keys load failsafe defaults or load optimized defaults press escape then press f10 to save to cmos to restart

hope this helps you

You have to format a hard drive with a third party disk unless its a usb data drive

The BIOS is AMI. Under ADVANCED SETUP:
The options listed for 1st,2nd ,3rd Boot device include:
IDE0 means Pri master
IDE1 means Pri slave
IDE2 means Sec master
IDE3 means Sec slave

Hope it helps you

To recover your motherboard bios and bring it back to life, you will need this following things:

1. Floppy Drive: It is needed to load the Boot Disk and the new BIOS update.
2. Boot Floppy: It is needed to load the basic operating system, preferably MS DOS.
3. ISA Video Card: Optional, but can simply the recovery process.

Notes:
A startup disk can be automatically built from the Add/Remove Programs applet within the control panel. The boot disk is a vital part of this guide, though users with WinNT/2K will need to build this boot disk from a system running MS-DOS or Win9x/ME.

You can obtain it also from this website: www.Bootdisk.com

Be sure to copy all needed BIOS utilities and update/backup files used during the original flash process to this disk as well.

After making the boot disk, delete the config.sys and autoexec.bat in the boot disk. It can be found in the disk primary directory path.

Create your own autoexec,bat. Using a notepad, build the autoexec.bat file by putting all the command lines in flashing a BIOS.

The approach for using flash utility from AMI or Phoenix is similar, but be sure to read the provided help information about each command line option before building the autoexec.bat entry. Create the text command entry, and then save to the file "autoexec.bat" in drive A: . This will load the command at floppy boot time, regardless of whether an ISA video card is available.

check the cables it properly connected or not. after start up press F8 key to check the installed hard drive is detected or not. if it is not, check with BIOS settings

Thanks Good Luck

BIOS Update Procedure
All latest Motherboards today, 486/ Pentium / Pentium Pro etc.,ensure that upgrades are easily obtained by incorporating the system BIOS in a FLASH Memory component. With FLASH BIOS, there is no need to replace an EPROM component. Once downloaded, the upgrade utility fits on a floppy disc allowing the user to save, verify and update the system BIOS. A hard drive or a network drive can also be used to run the newer upgrade utilities. However, memory managers can not be installed while upgrading.
Most pre-Pentium motherboards do not have a Flash BIOS. The following instructions therefore do not apply to these boards. If your motherboard does not have a Flash BIOS (EEPROM) you will need to use an EPROM programmer to re-program the BIOS chip. See your dealer for more information about this.
Please read the following instructions in full before starting a Flash BIOS upgrade: A. Create a Bootable Floppy (in DOS)
•With a non-formatted disk, type the following:
format a:/s
•If using a formatted disk, type:
sys a:
This procedure will ensure a clean boot when you are flashing the new BIOS.
B. Download the BIOS file
•Download the correct BIOS file by clicking on the file name of the BIOS file you wish to download.
•Save the BIOS file and the Flash Utility file in the boot disk you have created. Unzip the BIOS file and the flash utility file. If you don't have an "unzip" utility, download the WinZip for Windows 95 shareware/ evaluation copy for that one time use from _www.winzip.com or _www.pkware.com. Most CD ROMs found in computer magazines, have a shareware version of WinZip on them.
•You should have extracted two files:
Flash BIOS utility eg: flash7265.exe (for example)
BIOS eg: 6152J900.bin (example)
Use the latest flash utility available unless otherwise specified (either on the BIOS update page or in the archive file). This information is usually provided.
C. Upgrade the System BIOS
During boot up, write down the old BIOS version because you will need to use it for the BIOS backup file name.
Place the bootable floppy disk containing the BIOS file and the Flash Utility in drive a, and reboot the system in MS-DOS, preferably Version 6.22
•At the A:> prompt, type the corresponding Flash BIOS utility and the BIOS file with its extension.
For example:
flash625 615j900.bin
•From the Flash Memory Writer menu, select "Y" to "Do you want to save BIOS?" if you want to save (back up) your current BIOS (strongly recommended), then type the name of your current BIOS and its extension after FILE NAME TO SAVE: eg: a:13J900.bin
Alternatively select "N" if you don't want to save your current BIOS. Beware, though, that you won't be able to recover from a possible failure.
•Select "Y" to "Are you sure to program?"
•Wait until it displays "Message: Power Off or Reset the system"
Once the BIOS has been successfully loaded, remove the floppy disk and reboot the system. If you write to BIOS but cannot complete the procedure, do not switch off, because the computer will not be able to boo, and you will not be given another chance to flash. In this case leave your system on until you resolve the problem (flashing BIOS with old file is a possible solution, provided you've made a backup before)
Make sure the new BIOS version has been loaded properly by taking note of the BIOS identifier as the system is rebooting.
For AMI BIOS Once the BIOS has been successfully loaded, remove the floppy disk and reboot the system holding the "END" key prior to power on until you enter CMOS setup. If you do not do this the first time booting up after upgrading the BIOS, the system will hang.
BIOS Update Tips note: 1.Make sure never to turn off or reset your computer during the flash process. This will corrupt the BIOS data. We also recommend that you make a copy of your current BIOS on the bootable floppy so you can reflash it if you need to. (This option is not available when flashing an AMI BIOS).
2. If you have problems installing your new BIOS please check the following:
Have you done a clean boot? In other words, did you follow the above procedure for making a bootable floppy? This ensures that when booting from "A" there are no device drivers on the diskette. Failing to do a clean boot is the most common cause for getting a "Memory Insufficient" error message when attempting to flash a BIOS.
If you have not used a bootable floppy, insure a clean boot either by
a) pressing F5 during bootup
b) by removing all device drivers on the CONFIG.SYS including the HIMEM.SYS. Do this by using the EDIT command.
Have you booted up under DOS? Booting in Windows is another common cause for getting a "Memory Insufficient" error message when attempting to flash a BIOS. Make sure to boot up to DOS with a minimum set of drivers. Important: Booting in DOS does not mean selecting "Restart computer in MS-DOS Mode" from Windows98/95 shutdown menu or going to Prompt mode in WindowsNT, but rather following the above procedure (format a: /s and rebooting from a:).
Have you entered the full file name of the flash utility and the BIOS plus its extension? Do not forget that often you will need to add a drive letter (a:) before flashing the BIOS. Example: when asked for file name of new BIOS file which is on your floppy disk, in case you're working from c: your will need to type a:15j900.bin, rather than 615j900.bin only.
