Can't detect CD / DVD drive!! Can't run Live CD !!!

[ubuntu_seeker]

As with Array CDs 4 and 5, this release includes both the Install CD and the Live CD. This is scheduled to be the last Array CD release before the Hoary Preview. As such, we'd very much appreciate anyone who can test it to do so and file bugs on any problems you encounter.

Ok, bug / problem fix sought :

I'm booting Ubuntu Hoary Live CD (Array 6 and the MD5SUM checked out fine) and it boots ok and begins detecting various pieces of hardware but coughs on the CD/DVD drive, meaning, it could not find a driver for my CD/DVD so then I have to stop the installation. That is, I keep ending up back at the install menu where it says that the CD drive has not been detected yet. It asks me if I want to pick a driver from a list, and I've tried various ones "cdrom" etc. with no luck.

I've seen others post about this same problem in several places (at least 3 threads), but still there have been no replies... hoping for one soon.

My hardware is: Dell XPS Gen 3 (Pentium 4 3.6 GHZ), DDR-2 RAM, SATA 7200 rpm hard drive.

The CD-ROM is a CD / DVD RW combo drive... I believe it's an IDE drive.. listed in XP properties as "HL-DT-ST DVD+RW GRA-4120B".

MEPIS had no problem detecting my CD drive. And the drive works just fine in Windows XP SP2.

Thanks for any ideas!!! :^D.

I'd really like to be able to try out the live CD before installing Ubuntu. I'd much prefer to go with Hoary since Warty is kinda out of date by now.

I wish I could install Ubuntu

It's a hard one to know for sure. Try n=booting the CD with either (or both?) :

linux acpi=off

linux ide=nodma

Worth a try ...

[ubuntu_seeker]

I tried linux ide=nodma, but will try acpi...

Thanks for the suggestion!!!

All help greatly appreciated.

Is the drive set as a "Slave" on a port with no "Master" device?

If so, try changing it to "Master" and see if that makes a difference.

Hmmm... umm this is my main system hard drive, and I only have 1 drive. So I assume it must have been set to "Master" by the manufacturer, Dell, right? There are no other hard drives attached.

But I did see one guy said that Hoary Array 6 does not yet support SATA hard drives, and mine is SATA. Seems weird that a hard drive would stop the CD drive from being detected... especially when the CD is being *used* by the Live CD to even get to the point where it could detect the drive it is already running in...

Oh well, at least Fedora Core 3 works like a charm at work... ehe.

I'd like to try Ubuntu when SATA is finally supported.

I was referring to the CD/DVD, which I assume was a "standard" IDE drive.

Sometime your BIOS will boot off a Slave or Master drive, but the O/S later has problems if there isn't a Master.

In the past I've seen a lot of CD drives left set to "Slave" on the assumption that they will be plugged into the same cable as a "Master" hard drive.

If the hard drive is actually a non-IDE drive (like SCSI or SATA) then they don't bother to reconfigure the CD to "Master", basically because Windows doesn't care - even if some other things do!

[ubuntu_seeker]

How do you set the CD / DVD drive to be Master??

thanks

[ubuntu_seeker]

Ok, I checked in my BIOS and it says I have the drive on Parallel ATA (PATA) and that it is set to PRI(mary?) IDE Master... I suppose that means that the physical jumper must be set to Master on that drive.. I guess I may crack open the case later and check to see if I can tell.

So maybe the Master / Slave thing is not the problem...

Another guy with this problem said he solved it this way:

"I have this issue (also with a Dell), if you do a dmesg on the terminal and if you get something simular to this...

ide0: I/O resource 0x1F0-0x1F7 not free.
ide0: ports already in use, skipping probe
ide1: I/O resource 0x170-0x177 not free.
ide1: ports already in use, skipping probe

then thats looks to be the reason, I believe it's because the SATA driver is loaded before the ide-generic drivers.. Didn't get around it, but I installed Ubuntu by booting up from a gentoo CD, partitioned/formatted the drives and then copied the Ubuntu CD/DVD to one of the partitions.

On booting from the Ubuntu CD I mounted the said partition to /cdrom and then continued with the install.

Once installed I still got the same issue but followed this link to solve...
