Plextor CD-ROMs are slow to get ready after a reset or cold start, I've needed to increase the "Delay before BIOS scans device" in my Tekram DC-390U (default 3 s, options are 5 s, 10 s, and beyond up to 30 s IIRC, before I could boot from a CD in my Plextor PX-32TSi. The SCSI BIOS needs to provide the boot sector of the CD-ROM in floppy emulation for older PC BIOS, and some CDs don't run in emulation mode but boot directly, which doesn't work with older mobo BIOS... > I'm now using an Asus A7N8X-E mobo, which appears to have bios boot ...but I think the A7N8X should handle things fine... > settings only for SCSI in general, and not a particular type of SCSI > device.

Try increasing the delay between bus reset and bus scan, try switching off the bus reset. Note that I don't have a Flashpoint LT, so all I can say is play with the options. Some BIOSes need several options on to boot from CD. Note that this is not FreeBSD-specific AFAICS, so if you have further questions, please ask BusLogic or in some adequate newsgroup for help. -- Matthias Andree Encrypted mail welcome: my GnuPG key ID is 0x052E7D95 (PGP/MIME preferred)
