I am attempting to install linux 7.3 on a Dell BladeServer (1655MC).  I am booting from a usb Teac cd-219pu cdrom.  The system boots fine, but when I am asked where the files are located and I select 'other cdrom' it asks for a driver disk... why?

Thanks -- Tom

ps. I'm a beginning Linux user so I apologize for the question if it seems trivial.

First off -- not a trivial question.  Don't bother apologizing for asking a question -- that's what we're all doing here.

As for your problem, I have one question for you.  What distro are you using?  You say 7.3, but is that RedHat, Suse...?

It's RedHat

Well, I was hoping you'd say Suse -- I've got the 7.3 CD's for that and could have looked at the same menu you are.  Unfortuantely, I only have 7.1 and 8 for RedHat.  Here's what I can tell you though:

The Teac cd-219pu (bad letter choice [pu].  Oh well...) is not on Red Hat's hardware compatibility list.  So, there won't be any drivers specifically for that device in RedHat, and it may or may not work with RH.  Basically, it's unsupported. (Although it *may* work with generic drivers from Oak, Toshiba or another Teac drive).

If the menu gives you a few options for drive types, try out other drives.  If you like, list the contents of the menus (the one with the "other" option and the options under "other") and I'll see if I can help you.

To access the RedHat hardware compatibility list, go to


Just FYI -- as a system, the BladeServer is also not listed on the RH HCL.  This doesn't necesarily mean it won't run RedHat, just that it hasn't been tested.

Good luck and let us know if you would like more help with this.

i belive the issue lies with the fact that usb is not bootable with out an os behind it and drivers

I saw you tried RH8 and it worked -- fantastic.  If you want a brief explanation of what happened, here it is:

Booting from CD requires no drivers -- it's all done in the hardware and the boot loader on the CD.  No OS, no drivers.  So, the SYSLinux bootloader (I believe that's the one bootable Linux CD's use) was able to start just fine becuase your hardware supported that much.  But RH7.3 did not support drive, so once it started, the drive was no longer accessible.
