BIOS Updates forum

I have graved the bootblock only in the flash. The bootblock has launched with CS error message so only bootblock integrity is necessary to recover a bas flash bios. =============================================== I follow the same procedures with the lucky & asus board and it didn't work. Anyone ha...

First, thanks to Ruelnov and deniss for their help. I hope that message can help someone. I burned two flashes with Data IO tool, the first on with the bios and the second on with the bootblock only To avoid some addressing problem, I burned the same bios in the top (0--1ffffh) and the bottom (20000...

Do I understand this correct : - Both corrupted Bios are 256KB ones ans: Yes the both are corrupted - The GA-586SG-100 uses 128KB Bios and is not able to flash 256KB ones ans: that's right but I dont know if it is a bus address problem or an incompatibility between chipset and falsh programm - The e...

When I grave the flash with DATA IO, the location of the bootblock is on the low level of the flash (@ range: 3E0000 - 3FFFF for a 256 kb flash). This address should match with the reset vector of 80x86 which is FFFF0 (F000:FF00). In the bootblock, the reset vector is set with @FE05B (F000:E05B) add...

Thank you first for your reply As the bootblock alone can not run properly, it discard my first idea to grave only bootblock to recover the mobo. Normaly, I flash the totality of the bios binary file with Data IO. Do you think that flash utilities make something else? If flash utilities make some co...

I compare the 3 bootblocks of asus board (P3V4x) and I find always the same five bytes that are differents Comparaison des fichiers boot105.001 et boot1006.003 000000C5: 86 B6 00000102: 1A 48 000001C1: BC EA 00000256: 34 64 000014D2: 01 31 Comparaison des fichiers boot1006.003 et boot1006.004 000000...

Ok, it might be an explaination but do you think that when I flash the new asus bios including bootblock with data IO, the bootblock is not consistency with the old bios?

That could let say, that different versions of asus bios for a same board have no the same blockboot?

Thank you for your information First of all, bios has been graved with Data IO and not by award flash routine, so the bootblock has been superseed. I try to shortcut the Write Enable pin with A17 on asus and lucky bords but unfortunately it does not work (no beep, no access to floppy disk, no video ...

A friend of mine gave me 2 motherboards & a PIII (450) after of bad flash on each mobo. As I didn't know if the processor worked, I made a little program to generate a beep that use only registers. As it was working (config: no ram, no video), I concluded that the processor works even it does not pr...
