HELP!
        I am trying to install my SONY CDU-55E CD Rom Drive under linux
and I am having some strange errors. I am using an EIDE controller and the
CD ROM is installed as the master drive on my secondary controller (possible
problem source? Does it need to be a slave even tho it is the first drive on the
secondary interface?). The drive works great under DOS but I cant get linux to
access it. Here are the messages I get from startup:
(running 1.1.89 Kern and the hdc devices have been created)

Feb 16 02:04:31 PharCyde kernel: hdc: DCR-MOC UD55 E, ATAPI, CDROM drive
Feb 16 02:04:31 PharCyde kernel: hdc: IRQ probe failed (0)
Feb 16 02:04:31 PharCyde kernel: ide1: secondary interface on irq 15
Feb 16 02:04:31 PharCyde kernel: ide0: primary interface on irq 14

Then when I try to access the drive I get:

Feb 16 02:06:09 PharCyde kernel: hdc: timeout: status=0x51
Feb 16 02:06:09 PharCyde kernel: hdc: timeout: error=0x2c
Feb 16 02:06:19 PharCyde kernel: hdc: timeout: status=0x51

Feb 16 02:06:49 PharCyde kernel: hdc: timeout: status=0x50
Feb 16 02:07:19 PharCyde last message repeated 3 times

Feb 16 02:07:49 PharCyde kernel: hdc: DRDY error: status=0x48
Feb 16 02:07:49 PharCyde kernel: end_request: I/O error, dev 1600, sector 64
Feb 16 02:07:50 PharCyde kernel: isofs_read_super: bread failed, dev 0x1600 iso_
blknum 16

And Lastly I noticed that it says multimode disabled on my Hard drives! What
is this? I just noticed it:

Feb 16 02:04:31 PharCyde kernel: Partition check:
Feb 16 02:04:31 PharCyde kernel:   hda: disabled multiple mode
Feb 16 02:04:31 PharCyde kernel:   hda: hda1 hda2 < hda5 hda6 hda7 hda8 >
Feb 16 02:04:31 PharCyde kernel:   hdb: disabled multiple mode
Feb 16 02:04:31 PharCyde kernel:   hdb: hdb1 hdb2

ANY help will be GREATLY appreciated!

  Is it one of those port controlled eide cards?  Looks like the IRQ probe
the first error that the kernel encounters.  Try Loadlin and setup the
card in DOS and switch to Linux.  That may do the trick.  Make sure the
secondary IDE IRQ is set at 15.  Good luck!

CAN SOMEONE HELP ME TO SAVE MORE MEMORY TO REDUCE THE MEMORY SWAPPING?
YOUR HELP IS APPRECIATED.

I just bought a computer with 8 mega bye memory.  I thought I would be
happy to run X window on this machine.  This dream has been broken
by the frequence of memory swapping in/out.  My need is very simple.
I only want to run*(a type setting program) plus xdvi (a previewer
for LaTex) under X window, but the frequency of memory swapping makes
me feel I am abusing my hard driver.

I have done at least the following:
1. Recompile my kernel (drop the kernel image from 400+k to 200+K).
2. Use only one virtual console.  Only one agetty is invoked in run
   level 5, which is my defult run level.
3. Use ksh whenver it is possible. (ksh is much smaller than tcsh,
   bash, etc).
4. Remove xclock, goodstuff, etc from fvwm.
5. Turn off system log utilities in my rc.M
        /usr/sbin/syslogd
        /usr/sbin/klogd
        /usr/sbin/lpd
6. Use only one xterm window (i.e. my console) and run*over there.
   I tried to use rxvt instead of xterm but failed.  Rxvt only allowed
   me to create windows other than the console.  If I can invoke my console
   using rxvt rather than xterm, I can save more memory.
7. The last thing I tried is not to use any window manger, including fvwm.
   I can live with the odd looking of X window but I don't know how to
   make the active window (e.g LaTex) on the top of the other window (e.g
   xdvi).
8. Do you think using "nice" command can help a little bit?

The thing I haven't tried is to buy another 8 mega bye memory.

: CAN SOMEONE HELP ME TO SAVE MORE MEMORY TO REDUCE THE MEMORY SWAPPING?
: YOUR HELP IS APPRECIATED.

        Try using the XF86Mono Monochrome VGA X-Server.  This could
save enough memory to run*without swapping.  Stay with fvwm, it's
pretty memory-efficent.

        Good luck!

P.S.  Linux, X-Windows, and 16 MB go really well together, if you can afford
it...
