I asked on the list some days ago for help on ATAPI CDROM's because these devices are not recognized during installation. I've now finished my installation tests and will present you what combination is dedected and working. My test equipment are 4 PCs, P75, P200, PII-233, PII-450, all assembled with IDE HD and ATAPI CDROM. All PCs have different motherboards and different BIOS versions and functionality. Testet FreeBSD Distributions V 2.2.8, V3.1 and V3.2 HD CDROM STATUS IDE1, Master IDE1, Slave working IDE1, Slave IDE1, Master working IDE2, Master IDE2, Slave working IDE2, Slave IDE2, Master working IDE1, Master IDE2, Master failed IDE1, Master IDE2, Slave failed IDE1, Slave IDE2, Master failed IDE1, Slave IDE2, Slave failed IDE2, Master IDE1, Master failed IDE2, Master IDE1, Slave failed IDE2, Slave IDE1, Master failed IDE2, Slave IDE1, Slave failed Installing a second HD on the IDE controller, where the CDROM has been attached (in the 'failed' cases), has helped. The CDROM has been dedected. Conclusion: An ATAPI CDROM will only be dedected, if you install a HD on the the same IDE controller. I think, this should be treated as a _bug_ in the dedection routine of the kernel's ide part . As a comparison, I've tried to install Linux. Linux dedected the ATAPI CDROM in _any_ combination.
