Function EEH (0xEE or 238) --> Set 1024-Cylinder Flag (SWBIOS)
Call with: AH = EEH
DL = Drive Number
Return:
Carry Flag = Clear
AH = 00H
Comments:
The Function is used to Set 1024 – Cylinder flag. The flag is cleared by all INT 13H calls except AH=EEH and AH=EFH. Disk Manager also supports these calls. This function is equivalent to calling Function AH=EFH with CX=0400H for the software which supports that call.
This function is also supported by HyperDisk v4.01 and later, and PC-Cache v5.5 and later, in order to allow caching of drives using SWBIOS to access more than 1024 cylinders.
