Description margarita 1999-09-03 23:49:44 EDT

The cdrom prevents booting unless WIndows has been booted
and Red Hat boot is invoked without a power off.

When the system hangs on a cold boot the message on the
console refers to pc_cdrom is confused - lost interupt
reason 0x1. Values entered on Lilo have no effect on this
error.

Boot's OK on windows.

We will need to know more about your hardware. For example brand/model
of the cd-rom that you are having trouble with. Is it an ATAPI IDE
drive or a proprietary drive?

Comment 2 margarita 1999-09-18 12:55:59 EDT

I am using:
io magic 52x cdrom on ide 2nd slot as primary(not slave) /dev/hdc
   It is ATAPI as far as I know
   The 1st ide contains 2 drives 2.2GIG each - Western Digital

IWILL premium motherboard
64 MEG 60 ns EDO memory
One IBM 9.1 GIG SCSI drive.

More notes:

This condition existed before I installed the SCSI Drive.

IF I BOOT WINDOWS, AND THEN REBOOT RED HAT WITHOUT POWER OFF THE
CD ROM WILL WORK. IT WILL NOT WORK FROM A COLD - POWER OFF BOOT.

Hope this helps. I want eventually to get rid of the windows OS
entirely.

Comment 3 Patrick Monnerat 2000-02-08 12:48:59 EST

I have the same problem with RHL 6.1 and ATAPI/IDE CD-ROM as single (master)
unit on 2nd IDE controller. However, if I disable the recognition of the CD-ROM
drive at the AMI-BIOS setup level (but not the controller of course!), the
systems boot properly... Since I never succeeded booting an el-Torito CD-ROM
with this computer, I can imagine that this BIOS version does some dirty CD-ROM
initializations that DOS and WinNT reset, but not Linux... shame !

Comment 4 Ben LaHaise 2000-10-04 18:13:33 EDT

Is this still happening with the 2.2.16-22 kernel?

Comment 5 Brent Fox 2002-06-04 23:57:45 EDT

Closing due to lack of information.
