INT 13 - SWBIOS - SET 1024 CYLINDER FLAG
        AH = EEh
        DL = drive number (80h, 81h)
Return: CF clear
           AH = 00h
Notes:  the following INT 13 call will interpret the cylinder number as 1024
          less than the desired cylinder
        flag cleared by all INT 13 calls except AH=EEh
        SWBIOS is a TSR by Ontrack Computer Systems; Disk Manager also supports
          these calls
        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
