Hi folks, there have recently been some updates to FreeBSD's NCR
53c8xx SCSI driver, which I've ported over to NetBSD. The main changes
are:

     Add support for loading the SCRIPTS microcode into the on-chip RAM
     of the Symbios 53c825A, 53c875 and 53c895 SCSI chips.

     Submitted by:   Gerard Roudier <groudier@club-internet.fr>

     Add Ultra-SCSI support and enable more features for advanced
     Symbios/NCR SCSI chips (no-flush option, large fifo, ...).

     Submitted by:   Gerard Roudier <groudier@club-internet.fr>

For a more comprehensive list of changes, see
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/pci/ncr.c
I think the version currently in NetBSD is based on v1.93 of the
FreeBSD driver.

If you're interested in trying it out, let me know, and I'll mail you
a diff against -current. Be warned that so far, it's only been tested
on my machine, a Pentium with the following SCSI hardware:
