More SCSI Confusion

Right now I have two disks and one CD-ROM in my Alpha 433au (all attached to the internal ribbon cable, if you have seen my question about the storage shelf, that is not connected in this instance). The SRM recognises them correctly thus: dka0.0.0.1009.0 DKA0 COMPAQ ST32550W 6415 dka400.4.0.1009.0 DKA400 MATSHITA CD-ROM CR-508 XS03 dka600.6.0.1009.0 DKA600 IBM-PSG DDYS-T18350N M S96E However, when I start the Debian installer, during the boot sequence it does a SCSI reset and then only recognises the first disk, thus: scsi(0:0): Resetting SCSI BUS scsi0 : QLogic QLA1040 PCI to SCSI Host Adapter Firmware version: 7.65.06, Driver version 3.26 Vendor: COMPAQ Model: ST32550W Rev: 6415 Type: Direct-Access ANSI SCSI revision: 02 So, for whatever reason, the CD-ROM and the other hard disk disappear. I have checked the termination and it *seems* to be correct in that the disks and the CD-ROM are not (or *should* not) terminating anything. There is a terminator at the end of the SCSI cable, and I believe the QLA1040 SCSI adapter does its own termination: pka0_host_id 7 pka0_mode ultra pka0_soft_term diff Does anyone have any suggestions why the SCSI reset during boot should make the CD-ROM and the other HDD disappear?
