Message-ID: <BAY15-F19qEKApzbCeW0002e10a@hotmail.com> (raw)
I have attached dosdebug to dosemu when it hangs, and I got the following:
System state: running in real mode while in DPMI
AX=0000 BX=800a CX=0000 DX=0003
SI=874c DI=023a SP=056c BP=c316
DS=c316 FS=0000 GS=0000 FL=3286
CS:IP=0522:0434
SS:SP=c316:05bc
0522:0434 53 push bx
What should I do? Thanks.
