[S.u.S.E. Linux] IDE CD Drives...
-- Hello there... A rather awkward thing is happening in my system... let's see... I have a PII machine with a Intel LX board, a HD attached to the IDE0 port (/dev/hda), a CD-Rom drive at the IDE1 port as a master drive (/dev/hdc) and a Phillips CDD3610 CD-RW drive as slave at IDE1 (/dev/hdd). I use SuSE 5.2 The problem is the following: when I boot form the install (disk 1) CDRom from SuSE, everything is all right... at boot time the three ATAPI drives are detected. However, if I boot the installed precompiled kernel, or anyone compiled by myself, Linux does not see /dev/hdd... I get the following mess at boot-time (dmesg):
hdd: no response (status=0xd0)
and thereby I cannot access the CDRW not even as a single CD drive. What puzzles me most is why the installation disk recognizes it? Can anyone help me here?

There are quite a few reasons why the drive is not being seen. First of all, if the CD-ROM drive is made from Acer, it needs to be a slave on the Primary IDE Interface with the primary harddisk set to Master. That might be the case for some other CD-ROM's as well. If not, go into your kernel and check to see if you have selected the IDE-Atapi CD-ROM support. If that is not selected, then you will have to re-compile the kernel. Most kernels identify the CD-ROM device as a hdc, not hdd. However, from your message, you say that you can't access the CDRW, is that a CD Reader/Writer. Then if that is the case, then it is possible that Linux does not have support for a Reader/Writer. You will have to check with your Linux Distributor to see if the specific CD-RW device is supported and you can check the manufacturer as well. I do not see any other explanation. Hope this helps!

Try boot parameters: LILO boot: Linux hdb=none hdd=cdrom "man bootparam" could give you additional hints. I cannot explain why the kernel on the bootdisk works and the installed one doesn't. Maybe it's some timing problem (booting from HD is too fast). Also check your cabling. Many EIDE cables are too long.

Well, thanks everyone! Fiddling around the news I found some clues on my problem to avoid opening the case and switching drives... it seems to be related, as Hubert points out, to timing! The idea, if anyone has a similar problem is to override the AUTO setups in the BIOS for the PIO/DMA in the concerned drives. I could not figure out a rule, but it seems that setting 0/0 for both CD Drives works fine.
