BRAVO/386SX - SEAGATE 157A
|
|
|
|
|
|
Bravo/386SX systems which have the AST part number 500801-XXX may have
|
|
Seagate ST-157A hard drives installed. The AST part number for this drive is
|
|
230119-001. These drives are 40MB IDE type drives, which are configured as
|
|
drive type "17" in the Bravo's CMOS setup.
|
|
|
|
The following items are important for proper operation of the system but are
|
|
not documented by AST:
|
|
|
|
1. These drives are configured to operate as the main hard drive in a
|
|
system. They are not to be configured, and will not operate as a
|
|
"slave" to another hard drive which is installed as a "master" in this
|
|
system.
|
|
|
|
2. There is a jumper block on the control PCB labeled "J2". It is located
|
|
at the left rear of the board when viewing the drive from it's front
|
|
panel. It is comprised of three pairs of 2-pin headers labeled "1"
|
|
through "6". For use in this system the pair labeled "1" and "2" must
|
|
have a jumper installed. This configures the drive for a single drive
|
|
system. Also, the pair labeled "5" and "6" must have a jumper
|
|
installed. This enables the "external LED", sending the drive
|
|
activity signal to the front panel of the Bravo/386SX.
