The Bustek 742a controller? It appears that this card was heavily

used, back around 1992.

The mailing list archive shows 0 questions about this.  Given the
number of FAQs that are asked, I think this is pretty indicative of
the number of people using this card, i.e., few if any.

<question id="bustek742a-eisa-scsi">
<para>Why does FreeBSD not recognize my Bustek 742a EISA
SCSI controller?</para>
</question>
<answer>
<para>This info is specific to the 742a but may also cover
other Buslogic cards. (Bustek = Buslogic)</para>
<para>There are 2 general <quote>versions</quote> of the 742a
card. They are hardware revisions A-G, and revisions H -
onwards. The revision letter is located after the Assembly
number on the edge of the card. The 742a has 2 ROM chips on it,
one is the BIOS chip and the other is the Firmware chip.
FreeBSD does not care what version of BIOS chip you have but it
does care about what version of firmware chip. Buslogic will
send upgrade ROMs out if you call their tech support dept. The
BIOS and Firmware chips are shipped as a matched pair. You must
have the most current Firmware ROM in your adapter card for
your hardware revision.</para>
<para>The REV A-G cards can only accept BIOS/Firmware sets up to
2.41/2.21. The REV H- up cards can accept the most current
BIOS/Firmware sets of 4.70/3.37. The difference between the
firmware sets is that the 3.37 firmware supports <quote>round
robin</quote>.</para>
<para>The Buslogic cards also have a serial number on them. If
you have an old hardware revision card you can call the Buslogic
RMA department and give them the serial number and attempt to
exchange the card for a newer hardware revision. If the card is
young enough they will do so.</para>
<para>FreeBSD 2.1 only supports Firmware revisions 2.21 onward.
If you have a Firmware revision older than this your card will
not be recognized as a Buslogic card. It may be recognized as
an &adaptec; 1540, however. The early Buslogic firmware contains
an AHA1540 <quote>emulation</quote> mode. This is not a good
thing for an EISA card, however.</para>
<para>If you have an old hardware revision card and you obtain
the 2.21 firmware for it, you will need to check the position
of jumper W1 to B-C, the default is A-B.</para>
