Floppy Drives - Epson Equity 386SX Product Support Bulletin

Q22.
What extended hard drive support is available in the ROM BIOS that
comes with the Epson Equity 386SX?
A.
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 and the ST - 4096 hard disks, as well as, several ESDI
drives. By providing this support for 3rd party hard disk drives, the
Equity 386SX has the capability to use most 3rd party 8 - bit
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 Equity 386SX also has a User Definable setting that allows you
to set up hard disk drives that are not supported by the Equity
386SX 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
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.
