80 MB Smartdrive (250-4120)      Setup                 Faxback Doc. # 3086

The 2500XL, 4016DX, 4016SX, 4000SX, and 4020/25/33LX ROM's are configured 
for Drive type 28.

With Drive type 28 (977 cylinders, 10 heads) selected, the drive has a 
configuration of about 81 meg.  (Some of the newer ROM's have 981 cylinders, 
10 heads listed for Drive type 28.  This will not affect the operation of 
the drive.)  

On the MS-DOS machines that do not have drive type 28 or 35 in BIOS, it will 
give you a "Hard Drive Failure" error after each power up or reboot.  If the 
system boots from the floppy drive, the IDE drive can be accessed as normal.  

If you have a 3000NL with a BIOS ROM version that is earlier than 1.04.02,
the following applies:

Use Drive type 28, (8 heads, 1024 cylinders) and use SETUPNL1.  The IDE
drive capacity is about 68 Megabytes.  However, the 3000NL will give you
a "Hard Drive Failure" error after each power up or reboot.  If the system
boots from the floppy drive, the IDE drive can be accessed as normal.  

The recommended method is to upgrade the BIOS ROM to 1.04.02, and use
SETUPNL2 (a newer setup utility program).  Now you can select Drive
type 35 (not in earlier versions of ROMS).  The IDE drive capacity is
about 76 Megabytes.

When using Drive type 35 (9 heads, 1023 cyl.) you MUST put a jumper
on J14 of the IDE drive.  By placing the jumper on J14 you change
the head count from 10 to 9 heads, the cylinder count from 977 to
1023 cylinders.
