Subject: cdrom doesn't turn off
Date: 24 May 1999 06:32:18 GMT
I have a Philips PKM24X running on RH 5.2 and am having some problems with it.
The drive is ATAPI and works well exept the thing never turns off. If I put a
disk in and mount the drive and don't take the disk out for 5-10mins (after
using it) the door won't open. I have tried to unmount the drive (by typing
unmount /mnt/cdrom) and it doesn't do anything. Am I doing something wrong?
The documentation the came with the cdrom says it supports Ultra-DMA 33. Is
this standard on most computers? If I leave anything out please reply.
I am new to Linux and setting up hardware so descriptions are handy.

Sorry to follow up on my on post, but this should have been
mknod /tmp/hdb b 3 64 or
mknod /tmp/hdc b 22 0 if you like.

Booting Linux is as easy as inserting the install floppy and
pressing Ctrl-Alt-Del. The (slightly) more difficult part is
getting access to lilo and lilo.conf on your Linux root
partition. What I usually do when I lose the MBR on multi-OS
machines (assuming IDE disks):
- Boot off RedHat install floppy, tell it to install from local
CDROM and change to the shell (on console Alt-F2, IIRC) as soon
as it displays "in second stage install". Don't go any further
in the install procedure.
- Make a device node for the root partition. Use something like
"mknod /tmp/hdxn b <major> <minor>", where x denotes your hard
disk drive (a for the master on the primary IDE controller, d
for the slave on the secondary controller, etc), and n is the
partition number. Major is always 3 for drives on the primary
IDE controller and 22 for drives on the secondary, and minor is
(drive number * 64 + partition number). Drive number is 0 for
hda, 1 for hdb etc. For example:
mknod /tmp/hda1 b 3 1 or
mknod /tmp/hdb3 b 3 67
Also make a device node for the disk you want to re-install the
MBR on:
mknod /tmp/hda b 3 0 or
mknod /tmp/hdb b 22 0
- mount the device somewhere, like
mkdir /tmp/myroot
mount /tmp/hdb3 /tmp/myroot
- run lilo off the mounted partition:
/tmp/myroot/sbin/lilo -r /tmp/myroot
You have to tell lilo the mount point of the root partition if
it is not mounted at /. It'll chroot there for all it's
actions.
- Do a sync, unmount /tmp/myroot and press Ctrl-Alt-Del.
That's it from my recollection.
Hope this helps
Steffen.

I haven't noticed much improvement on the StarWriter input
filters between 5.0 and 5.1. Complex documents or those
containing in-line graphics are still broken.

Barry -
I use a Raritan Compu-Switch (model DDS1314) 4-channel unit. with great
success. It uses keep-alives to keep each OS fooled into thinking the ac=
tual
device (mouse or keyboard) is still "there", even when toggled over to an=
other
OS.
It's a pricey unit (~$590 U.S.), and cables are 6.5' ~$45, 13' ~$55
This is still much MUCH better than trying to make room for a bunch of
monitors, keyboards, and mice (not to mention the needed power outlets, e=
tc.)
You can get the Raritan from DataComm Warehouse.
Have fun. :)

They're giving away a trip to Antarctica to the developer of the "best"

BUT DON'T BE TEMPTED!
Their tool doesn't even RUN on Linux - it only deploys on Linux. You

ou can safely install both NT and linux on the same drive.
You want to install LILO onto the boot block where linux lives.
Meaning with the setup you've got,, I think, you would install LILO
into sda2. What you then need to do to get things to work properly
(so you can boot linux using nt's boot manager) is to copy the first
512 bytes of the boot record on sda2 and dump it into a file which is
then copied to your NT disk. You then need to hand hack the file
which NT uses to figure out where to find the OS's it should be
loading.
There is a howto on this which gives full command syntax.
Grab it from your favorite linuxdoc site (metalab.unc.edu?).
Good luck !

Subject: newbee, setup, & SCSI
Date: Mon, 24 May 1999 08:19:11 GMT
Hi, I am a Linux newbee and am ready to install a Caldera 1.3 version
but am having problems of a different nature:
I have a full scsi box,
Adaptec 2940 U2W
IBM Ultrastar LZX U2W
Plextor Ultraplex
Yamaha CD-RW 4416s
Celeron 300@450 on Abit BH6.
128 Mb Micron SDRAM.
On the HD there is already WinNT and Win98 in dual boot.
I would like to install Linux in a dedicated IDE HD which is in a
mobile rack and not as a dual boot option with Windows.
In order to avoid letter mixup drive letters in the Win scsi HD, when
I insert the IDE HD, I remove the cable from the scsi HD. Like this in
the system there is only ONE hard drive, the empty IDE.
Now I try to install Linux and after few screens too fast to be read,
the box reboots and starts from scratch...and on and on again
rebooting and restarting setup. I'm at loss understanding the reason
for this and how to solve it. Unfortunately, as I said, I'm a Linux
beginner....Thank you for your help,
Gianmaria

This is not entirely correct. On SMP machines the scheduler will try to
put the application on the least busy cpu. Even apps that aren't
multi-threaded will benefit since one cpu can do other things like run X
and all the windows etc. freeing up another processor to run the new app.
Whereas on a uniprocessor box the 1 cpu has to do everything thus limiting
the amount of time the new app in question would get were.
This a simplification but it hold true.
Now if you were meaning that the application in question itself would not
"span" cpus and thus get no benefit were it not multi-threaded then I
agree. But the original poster was asking for any benefit in performance.
Perhaps you are answering what he means and I am answering what he wrote?
Only he could clarify.

I checked the hardware connectors and everything is all right with them.
A different OS like Win NT/95 runs stable (as far as it can), though Win95
analyses an error in the ide port.
My question to You is: Is this an error of my kernel, of the harddisk or of
the mainboard (ide controller)? What can I do to check out, what is wrong?
Thanks a lot

If the connectors are the same as those on my ASUS P2B-S motherboard
(aic7890) they are Ultra2 SCSI and Ultra Fast and Wide SCSI for the two
68 pin connectors and Ultra Fast for the 50 pin connector.. If the
layout is the same, the Ultra2 connector is on the outside of the three
-- Ultra2 (68 pin)
Ultra Fast & Wide (68 pin)
Ultra Fast (50 pin)
