Hello.
I'm CvP,
I have an old computer with GIGABYTE's GA-BX2000 (Intel 440BX AGPset) motherboard.
It has dualBIOS and the problem is in DUAL-BIOS system.
Problem-
System doesn't boot. No display on monitor. No beeps from motherboard.
Changing the MB solves the problem.
How the Problem occurred-
After upgrading the BIOS, system can't boot.
When I installed WinXPpro
I got some error messages saying that
AMLI: ACPI BIOS is attempting to write to an illegal IO port address (0x4d1), which lies in the 0x4d0 - 0x4d1 protected address range. This could lead to system instability.
So I went to gigabyte's Website and downloaded a new version file for the BIOS... thought this'd solve all problems...
The files I downloaded are named [email protected] and bios_bx2000_f9.exe.
Previously I had f7 version and I downloaded f9.
Before upgrading, I saved the existing bios in my harddisk.
GWFLASH.exe said that I should save the file. If any problem occure, this file can be used to restore the BIOS.
Now after upgrading my BIOS nothing appears on monitor.
Since, system doesn't boot, I can't use that file to restore BIOS.
I remember some warnings saying that failing to upgrade BIOS properly(and with incorrect version) may lead to BIOS related problems.
But, in the Manual Page 42 it's written that,
"Q: Why does anyone need a motherboard with DualBIOS technology?"
Reason no 3 is
"If a user mistakenly updates their motherboard with the incorrect BIOS file, then the system may not be able to boot correctly."
and in page 44,
"During or after BIOS upgrade, if DUALBIOS detects that main BIOS is corrupt, the backup BIOS will take over the Boot-up Process automatically. Moreover, it'll verify the main and backupbios checksums when booting up. DualBIOS technology examines the checksum of the main and backup BIOS while the system is powered on to guarantee your BIOS operates properly."
Notice the Bolded text...I only continued with the upgrading because of this line in the manual or I would have never tried things like this.
Fixing the BIOS-
Now how do I fix it? If it can be fixed by some software methode, that's great, just tell me how to do. If it needs a hardware fix, please give a little description
Please, feel free to ask any kind of information you want... just help me.
