Agreed. But is the BIOS saying that because it hates the disk, or because it hates the FreeBSD bootblocks? > What drive is the FreeBSD boot drive being mappd to on the AIC7890? It's da0, which is disk 0 on the 7890. (Is that what you're asking?) It's on the Ultra2 bus, and works fine if I use the bootblocks on the floppy - just not the ones on da0. (Boot also fails in the same way if I connect the disks to the non-Ultra2 connector.) > You may want to pull the 2940 out if you aren't using it. Did that. The 2940 was already pulled the first time I met this problem. Its presence or absence has no effect, same error either way. Interestingly, at the suggestion of Guy Helmer, I noted the boot messages (from floppy kernel, and installed kernel booted off fd0's bootblocks) and the geometry reported in both cases was different to the geometry reported when booting from the 2940. For the record, here's the probe reported with the disks connected to the 7890: da1 at ahc0 bus 0 target 1 lun 0 da1: <IBM DCAS-34330W S65A> Fixed Direct Access SCSI-2 device da1: 40.000MB/s transfers (20.000MHz, offset 15, 16bit) da1: 4134MB (8467200 512 byte sectors: 64H 32S/T 4134C) da0 at ahc0 bus 0 target 0 lun 0 da0: <IBM DCAS-34330W S65A> Fixed Direct Access SCSI-2 device da0: 40.000MB/s transfers (20.000MHz, offset 15, 16bit) da0: 4134MB (8467200 512 byte sectors: 64H 32S/T 4134C) Thanks for your assistance, Doug (and Guy!) -- Phil Homewood DNRC email: philh@mincom.com Postmaster and BOFH Mincom Pty Ltd phone: +61-7-3303-3524 Brisbane, QLD Australia fax: +61-7-3303-3269 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
