Very Computer

I hate to ask this again, but I have more information, so thought it
would be okay...8)

I'm trying to install InfoMagic's Slackware 2.2, Kernel 1.2 Linux
distribution on CDROM.  I have a Reveal 4X CDROM on an IDE/TAPI
interface.  I created the boot diskettes as appropriate and boot, create
my partitions, and start the setup.  All goes well until it starts to
read from CDROM, I get an unexpected end of file and the following error
message on the console:

hdc: cdrom_read_from_buffer:    buffer botch (312575)
end_request: I/O error, drv 1600, sector 312575

I exited SETUP and changed to the mounted directory.  the files were
there as expected, but when I did a "cat" on a readme.lns and readme.dos
file, the file stopped and gave the above error message (different
sectors of course).  Because the sector's are changing, I don't think
it's the media, but I could be wrong.

Any insight would be appreciated!

Thanks

        I have the same setup (Reveal 4x & Infomagic Slakcware).  What I was
forced to do was to free up some space on my DOS-dedicated hard drive and copy
the disk sets onto that drive.  Then, I chose 'install from hard drive', and
everything worked fine.  **EXCEPT** that I still can't install directly from
the CD-ROM (BTW: you need the idecd1 or idecd2 kernal from the Q disk set).  
When I change to /cdrom and do an ls, I get the first five (or so)
directries.  Then, another ls gives me more, and finally a third ls gives me
ALL files and directories in the current directory.  I feel that this may be
related to my not being able to install off of the CDs.  Can anyone solve
THIS dilemma?

This is fixed in 1.3.x.
You can probably also make it work by mounting with a block size of 2k
(but you won't be able to run binaries directly off the cdrom in that case).

I don't think I can help you with your own problem, since I don't
know about InfoMagic, but I do have similar hardware ...

I just got a Reveal 4X CD-ROM multimedia kit, and already have Linux on my
system.  My Linux version is 1.2.3, and the actual CD-ROM is a 4X Goldstar (OEM)
GCD540, hooked into the SC400 through the IDE connector on the sound board
(for what its worth).

I tried the "sbpcd" version of the Linux kernel, but even with auto-probing,
and an attempt to define the I/O port, it didn't work. FAQs etc. don't mention
Reveal, with the exception of someone who got a different type of CD (Sony).
So which version of the kernel should I be using?
Anybody else got this same hardware to work with Linux?

BTW, I called Reveal tech support to get specs and info to help configure
the (right) kernel, and they said they "didn't support Linux".
He said that they "didn't have the drivers" (!!), and were afraid they'd
"have to support it" (!!!).  I tried to explain how Linux is different,
that if only the hardware manual had actual specs people could probably
figure it out and set it up themselves, etc., to no avail.
The tech person told me to return the kit to the store (!!!!).
Who am I to argue with qualified tech support. :-)

Your Goldstar is an ATAPI cdrom, and uses ide-cd.c. Configure your
kernel with IDE/ATAPI and it should work nicely. You will have to
mount CDs with blocksize=2048 if you are not using 1.3.x due to a
driver bug/feature of 1.2.x.
