Well, I also had some problems with my IDE CDROM being recognized. Here is
how I solved it.


I first installed FreeBSD - the kernel developer stuff - from a
DOS-partition. Then I recompiled the kernel, so it exactly had the same
configuration as my hardware. 

If you only have a IDE CDROM, and no IDE harddisk, then you should comment
out the wd0 and wd1 devices in the kernel-configuration file. For example

controller	wd	(something like that, can't remember it exactly)/
#device		wd0	at isa?
#device		wd1	at isa?

If you have an IDE-harddisk as master and the CDROM as slave, then you
should only comment out 'wd1' (wd0 = master, wd1 = slave). 
Well this worked for me... Of course you have to have an free DOS
partition in the first place. Don't forget to uncomment the 'option ATAPI'
stuff in the config-file.

I don't know how hard it is to make a new boot.flp with your configuration,
but I guess that one have make a whole new release to do that (make release!
*GRASP*).
