I have 2 completely different systems running FreeBSD which do not
recognize the CD-ROM drive at boot up using the install floppies. When I
say different, I mean different manufactureres CD-ROM drives, different
manufactureres IDE controllers, different manufactureres motherboards,
different BIOS manufacturers, etc. etc.
They both fail to recognize the CD-ROM drive with 2.1, 2.1.5 and 2.1.6.
They both WILL properly recognize the CD-ROM if I build a kernel without
the wd2 and wd3 devices defined.
I suspect this may have something to do with other peoples ATAPI CD-ROM
probe problems. Evidently probing for the non-existant hard-drives on
the controller screws up either the CD-ROM drive or the IDE controller
(I'm not sure which) such that the probe for the CD-ROM drive fails.
I think 2 things are needed here:
1. After a failed probe for an IDE device, the controller should be reset.
2. It should be possible to disable the wd devices from probing at boot
time.
I think if this is done, many peoples problems could be solved.
I have not had a chance to try the 2.2-GAMMA boot floppy yet. I
apologize if this is already addressed in 2.2.
