hello I'm trying to set "bios classic/dos" like state on the winfast 6300max/sis630 motherboard.
one of the issues I'm having is that it seems that interrupt 9 (keyboard) is not beging tiggered. (this is after linuxbios finish booting and I start bochs bios).
Initially I have suspected that the PIC in the sis630 is not getting programmed.
However, going over boch's bios sources I found out that it does DO program PIC..so it is not the issue here. (relevant code at end of email).
Thus the question is :
What is the extra step I'm missing that has to be run after linuxbios finish but before attempting to program PIC for bios/dos style interrupt mapping?
I don't quite understand your question, but LinuxBIOS does program the PIC to map IRQ 0-15 to INT 0x20-0x30. So the keyboard interrupt (IRQ 1) is routed to INT0x21. This is how Linux does for its interrupt handling.
