Hi. I want report that possible boot/install Win9x OS's on motherboard Abit BF6 with coreboot v4 + SeaBIOS master. After first reboot need boot PC from other OS e.g MS-DOS without AUTOEXEC.BAT and CONFIG.SYS and delete one line from file C:\AUTOEXEC.BAT on Windows partition (default FAT32 C:) like this:
----------------------------------------------------
mode con cp prepare=((852) ega.cpi)
mode con cp select=852
keyb pl,,keybrd4.sys   <----------- DELETE THIS LINE
MSCDEX.EXE /D:MSCD001
----------------------------------------------------
This is keyboard driver. On Abit BF6 with coreboot v4 this causes PC hang. After delete this line OS's boot OK :-).
On Win95 working driver GPU S3 Savage 3D (Fachman).
On Win98SE working Reboot from menu Start.
On both OS's some problems with install device drivers e.g. PCI or ISA.
