I have a Sony DVD-ROM DDU220E installed on my system. I have used it in the past to install from Red Hat 6.1. I had no troubles the first time I booted up linux. However, the second time I booted up linux, the kudzu program ran and removed the DDU220E from my configuration. I then attempted to reinstall the 6.1 distribution using this at the boot prompt: linux hdc=cdrom From there, the cdrom was detected like a normal ATAPI CDROM device. This resulted in recompiling the kernel, usually involving about 129 Megabytes or packages (I forget which it was). After recompiling, I rebooted linux and the cdrom worked. But after shutting down linux and rebooting, I used lilo to boot to linux and Win98 (so sue me). When I attempted to boot to linux, I get unkown atapi device with kudzu running, telling me its removing the DDU220E from my system. I have even considering putting this in lilo.conf: append="hdb=noprobe hdc=cdrom" (I'm not sure if it's quotation marks or single apostrophe's in the command line here.) But each time I recompiled using the installation method, I get the cdrom drive working just fine, it's just trying to keep the cdrom in the configuration file thats getting to me.
Choose 'keep the existing configuration' and you should be OK. What does the entry for the drive in /etc/sysconfig/hwconf look like?
closed, lack of input.
