Yes.  I used the driver that came with it.  It is a version that I don't
believe anyone other than AT&T source licensees have, SVR4 v3.0 and v4.0
Both v3.0 and v4.0 works with the 1542B just fine.  The card is
connected to a 486/33 (and also tested with a 386/20) - non-AT&T machine.

These machines were used to compile SVR4.  I can't really say much more
about the code, since our source license restricts me from disclosing
information.

I have a Dell machine here (the 486/33) running Dell SVR4 v2.01 but it is
using ESDI.  The 1542B was tested in the machine and Dell SVR4 didn't have
any problem recognizing the board and using it.  We are thinking of obtaining
the new Adaptec 1740 to use since the Dell box is EISA bus.  The current
driver is only for a 1542A (at least the driver source stated as such).  It
will need to be rewritten for the 1740, otherwise I assume I could use the
1740 in 1542B emulation mode.
