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".

SCSI BIOS Installed The Bios is installed under following
circumstances: 2. I can't get it to boot a HDD which boots fine form a
Future Domain. It is principally 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
Adaptec's 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. Using AHA-1640 in an IML System The IBM model 90 and 95 systems that are non-flash systems (Types 1, 2, and 3) require the use of an IBM made SCSI controller to store the IML information. Install the AHA-1640 as the secondary adapter, boot the machine using the IBM System Reference diskette and configure the AHA-1640 as the secondary adapter and set the BIOS to disabled. Ed.
IML systems depend on the Int4b function to
perform the Initial Microcode Load. With any non-IBM
SCSI adapter installed, the non-IBM SCSI adapter will be
scanned first (all of them have a lower I/O address than
the IBM SCSI adapters). Even _IF_ there is a bootable
device on the AHA-1640, it CANNOT perform the IML. Since
the IML is not completed, the system cannot scan for the
IBM SCSI adapter for the IML information. Result: System
hang. Accessing Onboard Utility and Multiple AHA-1640s > Adaptec onboard utilities are nice. [...] But don't exist on the MCA 1640...there is no "Control-A" for it, unless perhaps you tinkered with the ROMs. Nihavent Longa sounds off with: You can have multiple AHA-1640s in a system, as usual only one BIOS should be enabled. The BIOS will select as the boot device the host adapter with the lowest number physical slot among those having a 0 as the last digit of their I/O address (330h, 230h or 130h). If using auto-config, the adapter in the lowest slot will be selected as the boot adapter and assigned I/O address of 330h. If you want to use another adapter as the boot adapter, all adapters in a lower numbered slot than the boot adapter should have a 4 as the last digit in their I/O addresses, i.e. 334h, 234h or 134h. Again, only one adapter should have its BIOS enabled. Adapter BIOS I/O Port Address Arbitration Level Interrupt Level SCSI Address Sync Xfer Started by AHA-1640
