I suppose that if i am in real (or 'normal') cpu mode, then i can do 'int ?h'. I am not interesting what 'int ?h' really does - maybe long jump to ffff:0 etc. (Probably long jump to ffff:0 is one from more ways how to call bios function 'reset'.) I look at problem from my knowledge database about FreeBSD asembler (nothing) and about c+asm+bios under dos (good). I wrote mail, because i don't know FreeBSD-asembler syntax for a) and b) points - so I must look for it under /sys with undecided result. > Anyway, I have a BIOS reference somewhere at home, so just nag me and > I'll give you the address for the warm boot flag and the jump target. I don't need bios reference (I have it at home). To be continued next day...
