INT 13 - 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 SeeAlso: AH=F9h,AH=FEh,INT 16/AX=FFA5h/CX=1111h,INT 2F/AX=DF00h Index: PC-Cache;huge disks|Disk Manager
