What hard drive controller is used in the 386SX PLUS?

The 386SX PLUS uses a controller embedded on the hard drive. This

controller connects to a Task File Host interface (IDE) that is integrated in the

system board.

Can the 386SX PLUS use other hard disk drives and controllers?

Yes, the Host Interface on the system board can be disabled and other third

party hard drive controllers and drives can be used. The interface can be

disabled by setting Jumper J2 to position A. Other embedded controller AT-

type drives can also be used with the Host Interface.

What extended hard drive support is available in the ROM BIOS that comes

with the Epson 386SX PLUS?

The Seiko-Epson BIOS will directly support hard drives that range in size from

10MB to 153MB. There is direct support for the Seagate ST-251 as well as

several ESDI drives. By providing this support for 3rd party hard disk drives,

the Equity SX PLUS has the capability to use most 3rd party &bit and 16-bit

hard disk controllers. SCSI drives have their own controllers attached to the

drive and should work correctly when attached to the bus with a host adapter.

The 386SX PLUS also has a User Definable setting that allows you to set up

hard disk drives that are not supported by the 386SX PLUS Drive Type Table.

in SETUP, a sub-menu lists the settings you can change for each drive: the

number of cylinders (tracks), the number of read/write heads, the number of

sectors, the precompensation cylinder, the landing zone (the cylinder on

which you want to park the heads when moving the computer), and the total

storage capacity in megabytes. This allows you to use hard drives much

larger than 153MB.

FLOPPY DRIVES:

Q23. What types of floppy disk drives will work on the 386SX PLUS?

The 386SX PLUS comes standard with either a 5.25" 1.2MB or 3.5" 1.44MB

floppy disk drive. There is built-in BIOS support for industry standard 360KB

and 1.44MB, 3.5" half-height floppy disk drives as well as the 720KB, 3.5"

floppy drive. All four drive sizes are available from Epson.

Q24. Will the 386SX PLUS support 3 floppy disk drives?

No, not directly. The Epson controller and ROM BIOS supports a maximum of

two floppy drives.
