Sort of a strange problem and I wonder if it is with my IDE interface on
the motherboard. Here goes the situation:
1. The system finds my CD-ROM on boot no problem - from dmesg:
hdc: tOSHIBA CD-ROM XM-5502TA, ATAPI, CDROM drive
I have also used an NEC 3x with similiar results.
2. When I use my Caldera kernel that came from a CD that contained
RedHat 2.0 (??), I can mount a CD - it takes about 45 seconds though
for most CD's before I am returned to a prompt.
If I boot with a RedHat kernel (I upgraded from 2.0 to 3.0.3 using
the upgrade script and have built a new kernel) the whole machine
locks up completely and there is no breaking it when I try and mount
a CD.
3. Under the condition where I can actually mount the CD, things get very
strange. I was going to install Applixware today and thought I would
read the README file and gander at the install script. What I found
was several misspellings and strange characters on the screen! The
install script wouldn't even run because the word 'exit' and the word
'echo' was misspelled! As if the system had somehow mangled the
information.
4. I have had troubles using my CD-ROM since the start. I never could
get 3.0.3 installed and had to install the Caldera 2.0 RedHat and then
run the upgrade script to go to 3.0.3 (somehow it worked that one
time!) Similiar troubles when trying to install 3.0.3 from scratch
occurred (the machine would lock up or quit transferring data and
just die.)
I have built the kernel with iso9660 support properly and it recognizes
the CD-ROM drives fine. It is an IDE drive and the hard drives I have on
the 1st IDE interface are very happy. The CD-ROM is the master device on
the second IDE all by itself and uses IRQ 15. The only other major
devices on the system are an ethernet card using IRQ 11 and the mouse
using com 1 (IRQ 4) and the modem on com 2 (IRQ 3). Could my iso9660 support
be foo on the drive? Could the IDE interface be unhappy on the
motherboard? I have only used this machine for Linux so cannot say it
works with other OS's. I have purchased Applixware and RedHat 4.0, but
without a working CD-ROM they aren't much use right now! Any insights
and thoughts are welcome. If you have read this far, it is very much
appreciated. Thanks again to all!
