Odd. The problems you were seeing are to do with the BIOS level stuff, which is really independent of what OS you're trying to boot up. At a guess you actually did something a bit differently during the install. For future reference, one thing that has changed over time is using 'packet' mode (BIOS Int 0x13 extensions) -- this provides an alternative to CHS (Cylinder Head Sector) addressing as used in older BIOSes. Packet mode is appropriate for large disks, and allows you to boot from cylinders higher than 1023. It's basically the norm on any recent system with large disk drives. Problem is you need a BIOS with specific support for packet mode or it just won't work, so the default has always been to assume 'nopacket'. It has been mooted that switching the default to packet mode is an idea whose time has come, but that change wasn't made between 4.x and 5.x. See boot0cfg(8) for details of how to switch modes, but generally it's: # boot0cfg -o packet ad0 Cheers, Matthew -- Dr Matthew J Seaman MA, D.Phil. 26 The Paddocks Savill Way PGP: http://www.infracaninophile.co.uk/pgpkey Marlow Tel: +44 1628 476614 Bucks., SL7 1TH UK pgpy6bE8NGPhu.pgp Description: PGP signature

FreeBSD install on SCSI: Missing Operating System
I'm installing FreeBSD on an Intel ISP2150 dual 450 server with a Seagate ST39173LC 9GB SCA SCSI disk on an Adaptec AIC-7896 controller. I have no cd-rom, have created the two necessary floppies, and can install via FTP. the whole installation process goes smooth, but upon reboot, I simply get 'Missing Operating System'. I've googled for this, and searched the archives, but there is too much garbage about other operating systems interfering. I have found references to the auto-detected logical geometry being wrong. I see no user configurable options about c/h/s in the adaptec bios. FreeBSD's fdisk detects the geometry as: 8683 Cylinders/64 heads/32 sectors for 17782784 sectors (8683MB) I've tried making the root slice 250MB, 150MB, 100MB, and 90MB, each yielding no meaningful difference. Reading Charles Swiger's freebsd-questions post of 20040122, I have installed Windows 2000 Server on this machine; it boots up and runs fine. I'm simply stumped here and don't know what direction to head in. any advice?
