(See below, if you want to try it *now*). The driver is real and works well. It identifies my SCSI devices (2 DEC RZ25Ls and a TOSHIBA CD-ROM XM-3401TA) and I am now able to ignore my IDE drive (almost). Since my DEC EtherWORKS III driver is working and now I have a NCR 53C810 driver, my FreeBSD system is just about complete. (Now if only XFree86 supported the Diamond Viper.

Eg. completely reading a DEC RZ25L |>(535MB) with 'dd if=/dev/rsd0d of=/dev/null bs=64K' => 3MB/s sustained. |>We are waiting for the delivery of a new fast drive (>4MB/s) to be used |>for tuning and the test of advanced features (Tagged Command Queues). For those who care, the RZ25L test was conducted on a DECpc XL 466d2 with 32MB and the above hardware. The NCR 58C810 is built on the motherboard and so doesn't take a physical PCI slot. |>It compiles (at least) under 386BSD-0.1+patches and FreeBSD-1.1, and |>doesn't require any changes to Julian Elischer's generic SCSI driver |>(ie. its just a new chip level interface and thus can drive all |>devices supported by Elischer's code, not only disk drives). If you know how to build a kernel under FreeBSD, the driver is fairly painless to install. It's a nice piece of work. Too bad I don't have a WfW driver as nice the FreeBSD one! -- Matt Thomas Internet: thomas@lkg.dec.com U*X Networking UUCP: ...!decwrl!thomas Digital Equipment Corporation Disclaimer: This message reflects my own Littleton, MA warped views, etc.
