Right, Offset 2 from the Via-M VGA-Bios mvspd_15.rom is 0x7D 0x7D * 512 = 64000 Thats the correct image size before filling.
I have filled up this image with 00 to 65536 and will now try 0x80 for Offset 2
Where did you stick the checksum? Did you compute a checksum?
Mmhh, Offset 2 from mvspd_15.rom is 7D Offset 2 from a newer vga_bios.rom is 76
these are the correct values for the file sizes (Offset 2 * 512) after I extract they from the orginal Bios with award bios editor.
firstvga.rom is 64000 (7D * 512 = 64000) secondvga.rom is 60416 (76 * 512 = 60416)
with LinuxBios I use the firstvga.rom, because of the newer ones don't work with Linuxbios ( could be vgabios.c the reason? ), but after filling the file size is 65536
So I thought, I must set the Offset 2 to 80 (80 * 512 = 65536) and all will went fine with X (I hope so).
However, it does not work ;) Unfortunatly I get different checksums, always if I reboot.
For example,
85fd86, 8f753d
I don't no why, I use the same bios and the same configuration for the rest and get different checksums, that should be inpossible.
