I'm having trouble getting NetBSD-1.0 to recognize a NEC Multispin 4Xe
cdrom drive on bootup. My host adapter is an Adaptec 1742A, which sees
the 4Xe on powerup (but this only after disabling "Initiate Synch
Negotiation" on SCSI ID 2, which is where the 4Xe lives). Everything
runs fine under DOS, so at least something is working.

Has anybody else run into this problem (on sun-lamp maybe)?

Are there any other semi-secret gotchas in the EISA configuration for
the 1742A that I should be looking at? I've also set the Maximum Synch
Xfer Rate to 4 MB/sec and disabled Parity Check, both to no avail.

My machine is an i486-66 on an EISA bus with a Pheonix BIOS. For what
it's worth, a copy of my config file follows below. I realize that it's a
bit dirty.

The -current snapshot kernel-image disk boots on my machine, but
doesn't recognize the 4Xe either.

BUT, the 4Xe runs just fine under NetBSD-1.0 on my home machine, which
has an Adaptec 1542 on a PCI bus. 

This note is a revision of a message that was posted yesterday on
comp.unix.bsd.netbsd.misc. Since then I've had some e-mail from
someone (Robert Yoder) who thinks that the Adaptec 1740 class host
adapters have trouble with all NEC SCSI cdrom drives under NetBSD. Is
there a consensus out there around this point?

Thanks in advance.

PS: If someone can tell me how to get a Soundblaster 16 card running
under NetBSD-1.0, I'd be much obliged. This is a production machine,
so I'm a bit reluctant to install -current.
