ifplop.c32: Detect if PLoP USB/CD INT13h hook is enabled/disabled
New module which detects if the PLoP Boot Loader already has booted a
CDROM or USB drive by checking for the presence of the PLoP INT13h hook.
The following assembly code (NASM) can detect the PLoP INT13h hook:
mov eax,'PoLP' ; Reverse of 'PLoP'
mov ebp,'DKHC' ; Reverse of 'CHKD'
int 13h
cmp eax,' sey' ; Reverse of 'yes '
jz plop_INT13h_active
