About mouse, it turned out PS/2 emulation of USB devices was on in BIOS... I
disable it, but did not retry sudoku86.
Reboot: make a D exception after, saying it called int 28 or 28h... and after
saying it was ... cleaning DOS filesystems?... something like that.
Also LOADHIGH of UIDE.SYS seems to cause the same exception (at same address).
I disassemble part a little part of the code causing problem with debug:
e800:67f push es,eax,ebx,ecx,edx,si,di,bp
mov bp,ss
mov al,8d
out 70,al
mov ax,5000
mov es,ax
mov si,0
mov eax,es:[si]
add si,+4
mov ebx,es[si]
add si,+4
mov edx,es:[si]
push eax,ebx,ecx,edx
mov ax,cs
mov ds,ax
cmp di,+8
06c1: jnz 06c8
mov si,0658
6c6: jmp 06cb
mov si,0668
mov ax,5000
mov es,ax
mov di,0
xor cx,cx
mov cx,8
rep movsw
6da: lgdt [0678] point where exception happens
mov eax,cr0
or al,1
mov cr0,eax
jmp 6ea
6ea: mov ax,8
mov ds,ax
mov es,ax
mov eax,cr0
and al,fe
mov cr0,eax
jmp next line
etc.
I am uable to find reboot .com or exe ... where it is?
Where is the source code?
Oh also, this could help I think:
