Yes, IIRC LSI made a SCSI adapter based on the NCR53C875 chip.
SRM usually works with the Qlogic ISP1020/1040 chips too.

Or did LSI buy Symbios and with it the chip? I can't remember.

I have 4 refs of cards supported by SRM for AS series; XP more recent,
thus better support for larger variety.

what I use:
ISP10x0 (10, 20, 40, 80)
53C875, 53C876

For use with D1000, I use specifically a 53C875 by LSI, but it is also
manif by some other people.

You find a NON-EXHAUSTIVE table here:
http://moon.hanya-n.org/comp/alpha/hct/scsi.html
on.hanya-n.org/comp/alpha/hct/scsi-linux.html

(it lacks very old cards that work fine for me)

http://people.freebsd.org/~gioria/snap/CURRENT/src/release/doc/fr_FR.I...859-1/h
french, but easy to translate with google.

Those cards that work for me should work for XP1000.

A windows story:

I would love those tables to include P-ATA and S-ATA cards :s

22801 and 22802 also work fine (emdebing 53c875 from memory)
