Int 13/AH=EEh

SWBIOS - SET 1024-CYLINDER FLAG

AH = EEh
DL = drive number (80h, 81h)

Return:
CF clear
AH = 00h

Program: SWBIOS is a TSR by Ontrack Computer Systems

Desc: The following INT 13 call will add 1024 to the specified cylinder number to get the actual cylinder number desired

Notes: The flag is cleared by all INT 13 calls except AH=EEh and AH=EFh. Disk Manager also supports these calls. This function is also supported by HyperDisk v4.01+ and PC-Cache v5.5+, in order to allow caching of drives using SWBIOS to access more than 1024 cylinders. For software which supports that call, this function is equivalent to calling AH=EFh with CX=0400h
