The NCR 53c810 works well under FreeBSD, I know Linux support is being worked on by Drew Eckhardt, but I don't know about it's current state. (The FreeBSD driver is available from "FTP.Uni-Koeln.DE:packages/FreeBSD". It didn't make it into FreeBSD-1.1.5, but installs within a few minutes and there a boot floppy image and generic kernels are available in this directory if you don't want to build your own kernel. Reports from satisfied customers are available on request. :) I'd rather use the NCR than the BT964, since it is a low cost solution that offers best performance possible ! (Bonnie reports 30% cpu at 3MB/s transferred through the file system on a 486/66 (using a cheap 1GB drive). This corresponds to some 25 to 30MB/s at 100% cpu load on a fast Pentium system (ie. > 90MHz), or only a few percent in real world situations). Just make sure your motherboard has SMDS ROMS, or you won't be able to boot from SCSI disks ... -- Stefan Esser Internet: <se@MI.Uni-Koeln.DE> Mathematisches Institut Tel: +49 221 4706010 Universitaet zu Koeln FAX: +49 221 4705160 Weyertal 80 50931 Koeln
