Did you run as root depmod -ae ? Does it indicate anywhere in dmesg that it recognized your cdrom drive and where it's connected?

I tried the depmod -ae, it returns nothing, so I'm not sure what it actually did. It looks like my cdrom is recognized in dmesg. I just recompiled my kernel, but still no dice. here's a bit of my dmesg:

ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx

Here's my new fstab:

/dev/hda1 /mnt/ntfs auto defaults 0 0

[edit] one more unrelated question; I notice at the top of the dmesg, there is the "ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx". where do i override the 33mhz setting? would this possibly be a reason my hdparm -Tt scores are so shitty?

I encountered the same problem as u.

Did you fix it? How?

Did the cdrom drive work with the original kernel? I've never compiled a kernel before. Maybe you left something out.

As for ' idebus= ', it just tells the linux ide driver what the bus speed is. It can't change it. I found that explanation here .

Considering it says this: "override with idebus=xx", I'd be willing to bet you can override it. I didn't follow you r link past the first page, maybe I will tomorrow, I"m ripped now.

To answer your question, I'm not sure if the cd ever worked. I never wanted to use it till now. It's always worked off the boot, so I've been under the assumption it worked till i tried to use it for the first time.

Btw, what's a good cd buring program to use? I'll mostly be burning divx .avi's to cd to watch at work. Some music cd's mostly data cd's is what I plan to burn. I've got Fireburner, but it appears it's only shareware. Buying softare defeats my whole intention of migrating to linux.

I too have tried the depmod -ae suggestion, along with the modprobe cdrom. I'm not sure what else I can do. It seems this is a problem with ATAPI cdrom burners (as seem on the redhat bugzilla messages), but I'm not sure if someone has discovered a solution. If anyone has gotten their ATAPI cdrom to work under Redhat 7.2 please reply and help us out. Thanks in advance.

Maybe this thread will help.
