F1 - From Peter- The fuses are Schurter
(Switzerland) microfuses of the MSF-125 series, order no. 0034.9875 - a
single package is 10 pieces at 125V / 1.6A, rated "quick acting F". Schurter
has an internet page with product catalogues in .PDF at www.schurter.ch
(Ed. A PTC resistor might work here
as well)
Connectors
J6 - Internal 50 pin SCSI cable connector
J7 - External 50 pin mini Centronics SCSI port
Transfer rates
Up to 8 MBytes/sec bus master
DMA on the Micro Channel bus
5 MB/s synchronous burst
or 2 MB/s asynchronous burst on the SCSI bus
RAID Support
The AHA-164x supports RAID Level 0, 1, and 5 with the help of third
party software. Ed. Whose software?
W95 and DMA Channels
It seems as if W95 has the choices of DMA Channels 5,
6, and 7 available. You may have to go into the System Programs (a.k.a.
Setup) and change the Arbitration Level to one that W95 is looking for.
No SCSI BIOS Installed
1. The AHA1640 says no SCSI BIOS installed. The chips are
there on the card.
The Bios is installed under following circumstances:
- no "drive C: " (Hex-80 device) previously installed
- drivesize is 1GB or below
- BIOS is enabled under the machine setup and on a valid adress
2. I can't get it to boot a HDD which boots fine form a Future Domain.
If the drive is over 1GB and / or low-level
formatted with a different
translation schem it will not be recognized anyway. The Adaptec Boot
BIOS is
"old fashioned" and has a 1GB-limit.
It is principially the same as used on the ISA AHA-1540B
(not -C or -CF) and has no CTRL-A support and uses the DOS-compatible HD
translation, which is a bit "register-width challenged".
You need to LL-Format the drive with Adaptecs SCSIFMT
... which requires a boot disk with the ASPI4DOS.SYS to have the drive
under ASPI-Manager control. The ASPI Manager is capable to handle drives
over 1GB - the Boot-Bios isn't.
Adapter BIOS
Memory location of the adapter's BIOS ROM. Note, if two
AHA-1640 host adapters reside in the system, one of them must have its
BIOS ROM disabled.

Sync Xfer Started by AHA-1640 Yes/No
Synchronous transfer on the SCSI bus will be started by
the adapter if 'Yes'.
<Yes>, No
SCSI Parity Checking On/Off
The host adapter will check SCSI Parity if
'On'
<On>, Off
Fairness On/Off
Bus Arbitrations Fairness. This controls whether the adapter
will release control of the bus when it has been using it exclusively.
