>Description:
System is a Compaq Workstation 5100 with dual PCI buses (ServerWorks chipset), dual PII 333MHz CPUs and 384MB RAM.

IDE controller is on motherboard (unidentifiable chipset) and has only a secondary channel connector for IDE CD-ROM. The IDE CD-ROM is a Compaq/Matshita CR-5850.

System correctly boots from IDE CD-ROM (ie from BIOS) - but IDE CD-ROM is not found during device probing.

NB CD-ROM suffered similar problem to PR 43762 - hence is probably controller issue???

dmesg (verbose) extract from 5.2.1-RC2:

dmesg extract from 4.9

>How-To-Repeat:
1. Boot system with FreeBSD v5.2.1 disk in CD-ROM
2. Observe CD-ROM is not found during device probing

>Fix:
Unknown (yet).
