SWBIOS - GET EXTENDED CYLINDER COUNT

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

Return:
CF clear DX = number of cylinders beyond 1024 on drive

Program: SWBIOS is a TSR by Ontrack Computer Systems

Notes: Standard INT 13/AH=08h will return a cylinder count truncated to 1024. BIOS without this extension would return count modulo 1024. Disk Manager also supports these calls
