394 | * P.S. There are no exits or event injections taking place when DS gets
|

395 | * corrupt, the last exit was a CR0 read in OS2KRNL's DOSSEG (0120:1798)
|
---|
396 | * probably related to we comming back to protected mode from real mode as we
|
---|
397 | * just made an APM BIOS call.

399 | * Update: The values loaded off the stack aren't the ones ending up the
