8 BIT CONTROLLER HARDWARE PROBLEMS
The following are details and possible remedies for the hardware
incompatibilities we have encountered:
1. The port address of the PS180 is at 320 Hex. In 286 and 386
computers during boot time with the C_MOS set to "no hard
disk drives installed", the system will step up through the
memory map until it finds a device (BIOS ROM) that will take
over. The Perstor BIOS, addressed at C800:0, will finish the
boot sequence.
2. WD 1002 Fox Floppy controllers do not work with the PS180.
Use a different stand alone floppy controller or replace it
with the WD 1003 dual floppy/hard disk card. We recommend
using a stand alone floppy disk controller such as the Kouwe
Model KW530. It supports 360K, 720K, and 1.2MB floppies in
286 computers only.
3. The Everex tape backup board must be set to DMA 1 if used
with the Teac tape backup machine.
4. The IBM BIOS used on clone system boards will display the F1
message. You must exchange this BIOS with one designed for
your specific motherboard. We suggest using a Phoenix BIOS.
5. With a Copy II PC option board installed in an XT or
compatible system, the interrupt level must be changed
because a conflict exists with the interrupt of the PS180
controller.
6. The IBM XT BIOS dated November 2, 1982 will display the F1
error message. You must exchange this BIOS with a newer
version of the IBM XT BIOS.
7. Syquest 12MB SQ312R removable cartridge drives must have the
following modifications made: the W3, W8, and W9 positions
must be open for proper operation with the PS180.
8. If you are installing two Seagate hard disks, leave both
terminating resistors intact. This will allow the Seagate
drives to perform more efficiently.
9. Micro Science HH1120 RLL drives dated August 1988 and later
with a 100+ nanosecond pulse width require a modification to
the Perstor controller with artwork revisions below 3.0 for
proper operation. Call your dealer for details.
10. Some system board BIOSes (such as the DTK) that support 3.5"
floppy drives will be incompatible with the PS180. These
problems are currently being addressed. The DTK BIOS with 3
1/2" floppy support is compatible with the AT9-1.03 BIOS, but
the clock will reset the minutes to 00 during the boot phase.
The AT9-1.07 BIOS will correct the clock problem, but 3.5"
floppy drives will not be supported.
