BIOS Upgrades - shit!

Hvis du er bare lidt heldig kan det lade sig gøre at redde BIOS sådan:

Pil alle drev undtagen floppy fra
tag alle kort ud
Isæt et ISA skærmkort
Tænd maskinen
Hvis du kan komme ind i BIOS herfra, kan du flashe BIOS med den rigtige version

eller tag batteriet ud og start den op, vent lidt. sluk den og tænd for den.....

Jeg har prøvet begge dele nu, men ingen af dem virker - andre gode ideer?

Slå dig selv meget hårdt oveni hovedet med dit bundkort.. :)

Nej. Du kan undersøge hvad en ny bios chip koster, men den er som regel ikke ret billig!

Jeg HAR slået mig selv i hovedet + alle dem der sidder omkring mig :)

Læser artiklen lige nu, men kom endelig med mere input hvis i kan!

Hvis du har et bundkort med en BIOS af samme type og er MEGET desperat, kan du tage chippen ud af dit bundkort, sætte den i det andet bundkort og resette den. Sæt den derefter tilbage... Skulle virke.
Jeg har haft samme problem, da jeg ikke var så klog med computeren... Prøvede at flashe BIOS i en ustabil Windows 95 via kommando-prompt (gæt, hvad der skete!). Jeg opgraderede istedet for at rode med BIOS...

Jeg kender ikke det omtalte mainboard i detaljer?

Prøv evt. først følgende:

-Hvis bundkortets system-ur bliver forsynet med strøm:

1. -Fra 3V CR2032 batteri? -Så fjern batteriet og sæt det først i igen dagen efter. -Forsøg opstart. -Gå ind i bios og load bios-default.

2. -Fra opladelig batteri? -Bør du kunne se i bundkort-manualen, hvordan du resette bios.

Prøv det først? -Hvis det ikke hjælper?
-Så vil jeg gerne have oplyst navnet på din bios og din bios-id.
-Fortæl hvordan du har forsøgt at opgradere din bios?

Håber det hjælper dig på vej?

How can you recover a corrupt BIOS ? 

Solution 1: Boot-block BIOS

Modern motherboards have a boot-block BIOS. This is small area of the BIOS that doesn\'t get overwritten when you flash a BIOS. The boot-block BIOS only has support for the floppy drive. If you have a PCI video card you won\'t see anything on the screen because the boot-block BIOS only supports an ISA videocard.

Award: The boot-block BIOS will execute an AUTOEXEC.BAT file on a bootable diskette. Copy an Award flasher & the correct BIOS *.bin file on the floppy and execute it automaticly by putting awdflash *.bin in the AUTOEXEC.BAT file.

AMI: The AMI boot-block BIOS will look for a AMIBOOT.ROM file on a diskette. Copy and rename the correct BIOS file on the floppy and power up the PC. The floppy doesn\'t need to be bootable. You will see the PC read the floppy, after about 4 minutes you will hear 4 beeps, this means the transfer is done. Reboot the PC and modify the CMOS for your configuration.

Solution 2: Get a new BIOS chip

Contact your motherboard manufacturer to see if they sell BIOS chips. Some motherboard manufacturers send them for free.
Contact a company that sells pre-flashed chips, like Unicore Software, FlashBIOS.ORG or BadFlash
Solution 3: Hot-swapping

Note: I\'m not responsible for any damage this method may do to you or your computer !

Replace the corrupt chip by a working one. The best option is to take the working BIOS chip from a motherboard which has the same chipset although that\'s not absolutely necessary. It just has to give you a chance of booting into DOS. Before pulling the working BIOS chip out of it\'s original motherboard, set the System BIOS cacheable option in the BIOS to enabled.
After you have put the working BIOS in the motherboard with the corrupt BIOS boot the system to DOS (with a floppy or HD).
Now replace (while the computer is powered on) the working BIOS chip with the corrupt one.
Flash an appropriate BIOS to the corrupt BIOS and reboot.
Note: Use a flasher from MRBIOS. They are known to work best. You can find them at ftp://ftp.mrbios.com

Solution 3: (for Intel motherboards)

Change Flash Recovery jumper to the recovery mode position (not all products have this feature)
Install the bootable upgrade diskette into drive A:
Reboot the system
Because of the small amount of code available in the non-erasable boot block area, no video is available to direct the procedure. The procedure can be monitored by listening to the speaker and looking at the floppy drive LED. When the system beeps and the floppy drive LED is lit, the system is copying the recovery code into the FLASH device. As soon as the drive LED goes off, the recovery is complete.
Turn the system off
Change the Flash Recovery jumper back to the default position
Leave the upgrade floppy in drive A: and turn the system on
Continue with the original upgrade
