I'm running Linux on an HP Vectra 486/66 XM. It works just fine.
|
|
|
|
Someone else said that they were never able to get the onboard ethernet
|
|
controller to work... I initially had this problem, but I grabbed a
|
|
patch that was posted to C.O.L.A that fixed it.
|
|
|
|
I don't recall the exact details, but it involved patching a single
|
|
file (lance.c). You can probably find it on sunsite.
|
|
|
|
The only other problem I encountered was getting the mouse to work.
|
|
It's a bus mouse and I had some weird conflicts with the mouse under
|
|
X, but only when the onboard ethernet was enabled.
|
|
|
|
But changing some CMOS settings cleared it up. It's been a while and
|
|
my memory fails me, but I believe that I ended up changing the ethernet
|
|
IRQ.
|
|
|
|
Finally, I had to change the IRQ used for the bus mouse and recompile
|
|
the kernel.
|
|
|
|
If you do get the HP, feel free to contact me via e-mail for the
|
|
specifics.

You are, of course, correct, and this is the way I have it set up now.
|
|
The problem is, w (and other commands) look much better if they return
|
|
just the first part of the name (so I'm aesthetic--sue me :). On Ultrix
|
|
you can evidently use this format:
|
|
|
|
ip short-form fqdn aliases
|
|
|
|
and it will use the short-form for stuff like w, but can still find the
|
|
machine's fqdn.
|
|
|
|
Maybe the best answer is to recompile w... <grin>

I have a setup (still installing) that works nicely with big drives...
|
|
|
|
/dev/hda has 1322 cylinders, 16 heads, and 63 sectors.
|
|
/dev/hdb has 2100 cylinders, 16 heads, and 63 sectors.
|
|
|
|
I booted with an older boot/root floppy set (kernel 1.0.0, slackware...)
|
|
using the lilo line (recommended for PS/1 users in the preboot message)
|
|
boot: ramdisk hd=1322,16,63
|
|
and it loaded up, recognizing my first hard drive (that already had one
|
|
240M MS-DOS partition).
|
|
Next I ran fdisk (linux) to create a second MS-DOS (*)primary partition
|
|
of 240M. * - MS-DOS FDISK.EXE will only create one primary partition, the
|
|
rest have to be inside an extended partition.
|
|
I then rebooted into MS-DOS to format the new drive. (to verify it worked)
|
|
So far, so good... everything fuctions perfectly. Reboot into linux, using
|
|
the same command as before...
|
|
I then used linux fdisk to create a ~24M swap partition and ~145M linux
|
|
native partition... Reboot again, mkswap & mke2fs etc. perform minor install
|
|
and reboot into MS-DOS to verify everything still works... no problems! :)
|
|
Next, using loadlin, boot linux (loadlin 1.5 is from heaven!!) with the
|
|
appropriate root=/dev/hda4 line... perfect! Run fdisk, and guess what?!
|
|
Linux (1.0) not only knew the *correct* size of hda, it also knew hdb!
|
|
(I thought I would have to have 1.1.50+ to automatically recognize them! :)
|
|
|
|
So far, with this setup, I have _no_ device drivers loaded, and 480M set up
|
|
for MS-DOS, and Linux filling the rest of the space on the disk with no
|
|
problems! I could have up to the MS-DOS limit (504M) using this method...
|
|
|
|
|
|
Here are the oddities...
|
|
|
|
After creation of the last partitions, if I load FDISK.EXE my partition
|
|
table lists the linux native (cyl 1025+) partition first, then the two
|
|
FAT partitions, then the swap. Apparently MS-DOS strips 1024 from the
|
|
number in the partition table, and then thinks the partition is at the
|
|
beginning of the disk. It seems to function properly, and since MS-DOS
|
|
cannot access anything over 1024, my linux partition is safe. Since linux
|
|
is intelligent enough (what did you expect? :) to recognize cylinders above
|
|
1024, my MS-DOS partitions are safe. (except from the virus MS-Windows ;)
|
|
|
|
When creating a partition in the _second_ drive with FDISK.EXE, the
|
|
second partition in the _first_ drive was no longer recognizable by
|
|
FDISK.EXE or MS-DOS. :( Well, I tried checking the partition table with
|
|
linux fdisk, it was OK. hmmm... Next step was to delete the MS-DOS
|
|
partition from the second drive: POOF! like magic my second partition in
|
|
the first drive is now an MS-DOS partition with a readable volume name again
|
|
(FDISK.EXE) and everything is working again. I tried making an extended
|
|
partition on hdb to host the MS-DOS partition. (thinking MS-DOS can only
|
|
have two total primaries) No luck, same problem. I deleted the MS-DOS
|
|
partition from the extended partition (left the empty extended partition)
|
|
and the problem still wouldn't go away. I deleted the extended partition
|
|
and POOF! (again) it worked. (linux worked in all instances! :)
|
|
|
|
Does anyone know enough about the partition tables to know why the creation
|
|
of a partition on hdb can effect the partitions on hda? Are they both stored
|
|
on hda? (I thought each drive had it's own partition table)
|
|
|
|
You're welcome for the install advice, and
|
|
thank you for any help any of you might offer me...
|
|
I plan to work on it some more tonight when I get home, so
|
|
I will try to keep you updated as to my 1.7G install. :)
|
|
(gotta love these drive prices!!)

|
|
|

I have an Intel chipset P5-90 motherboard with a Herc PCI video card with an
|
|
ET4000/32W chip. The docs say it works but sometimes I get a flicker when
|
|
going into X and then a black screen. I can escape out with ALT-CTL-BSPC. The

system works great in Dos Mode and running Windows, in all resolutions. Once
|

in X, if I can see it, it works great, never even a little flakey. It seems to
|
|
not work in batches, maybe a few times, then works great for a while. I have
|
|
tried two different motherboards and two different video cards. The version of
|
|
Linux is the Yggdrasil Plug-N-Play, Fall Release.
|
|
Any ideas???
|
|
I check this group but wouldn't mind an email if you got a fix.

You need to have a boot disk that gives you the LILO boot: prompt. At that
|
|
prompt, type:
|
|
|
|
ramdisk aha152x=0x340,11,7,1
|
|
|
|
Then, when you get Linux installed, you will have to install LILO and
|
|
add the following line to the /etc/lilo.conf file:
|
|
|
|
APPEND='aha152x=0x340,11,7,1'
|
|
|
|
That should ge you up and running.

It's a matter of taste. One can decide to have the computer (controlled by you
|
|
and your wishes) to control the modem. Or one can decide to let a dump machine
|
|
(the modem) react in a sometimes annoying way for the caller (e.g. if there's
|
|
no getty - or such - running..).
|
|
|
|
In short: It's a decision if one uses the (imho better) possibilities that

|
exist or not.

Hi All,
|
|
|
|
well, a little late "bug" report which may be already obsolet, but still may
|
|
help some fellows out there.. What I'm talking about:
|
|
|
|
Having the N disks (Slackware v2.0) installed one finds a file /etc/named.pid
|
|
on the hard disk, indicating that this will show the pid of named (if started).
|
|
So far, so good. BUT!
|
|
|
|
/usr/sbin/named does use/create its named.pid in /usr/tmp, not /etc !
|
|
|
|
The scripts /usr/sbin/named.restart|reload (they have softlinks in /etc) have
|
|
to be adjusted to use the right named.pid (and also to the path for named
|
|
inthere is wrong) or one may get some unexpected "surprise"..

Yes, I have RTFM (Ftape-HOWTO) but this tape drive is not listed

Disk partitioning and moving filesystems.
|
|
=========================================
|
|
|
|
Firstly I must mention that I have read
|
|
Wirzenius's newsarticle of 2 jul 1994 18:21 about disk partitioning.
|
|
|
|
However I have some questions.
|
|
|
|
I recently bought a 420Mb Conner ide drive.
|
|
And I have a 240Mb Samsung ide drive.
|
|
|
|
Currenly my 240Mb Samsung drive is my hda
|
|
and my 420Mb Conner drive is my hdb.
|
|
|
|
The partitions are:
|
|
Filesystem 1024-blocks Used Available Capacity Mounted on
|
|
/dev/hda2 216012 173057 31799 84% / % linux root
|
|
/dev/hdb1 385436 1 365529 0% /hdb1 % new linux part
|
|
/dev/hda1 5212 2636 2576 51% /dosc % dos part
|
|
|
|
On /dev/hdb2 I have a 18Mb swap partitition.
|
|
Earlier I had a 17Mb swap partitition on /dev/hda3,
|
|
but that I deleted.
|
|
|
|
Since the 420Mb Conner drive is faster I would
|
|
like to let this become hda(by changing jumpers on the drives).
|
|
Then would like to have one big linux partitition on this,
|
|
besides the swap partitition.
|
|
|
|
On 240Mb Samsung drive I would like to have a small
|
|
dos/mswindows partitition and a news spool partition
|
|
since I am planning to set up a news server on my box when I get
|
|
my slip connecting.
|
|
|
|
How can I accomplish this?
|
|
|
|
Especially installing lilo on the 420Mb Conner drive.

Actually, in the ever running catch up game between AMD and Intel the price
|
|
difference has fallen to $20. BUT, this is about to change--BIG SHOCK!! 8^)..
|
|
|
|
AMD is about to release, yes you guessed it, their 486DX2-80MHz!!!!!
|
|
|
|
From what I've heard through my venders, It will run about $20 more than an
|
|
Intel 66MHz.

It doesn't matter if you're running X, MS Windows, OS/2, NT or any other GUI
|
|
that you can think up, upgrading from 4 to 8 Mb of RAM is worth magnitudes
|
|
more than the cost of the upgrade. I've have seen (on the high, exagerated
|
|
end of examples) as much as a 60% increase in performance.
|
|
|
|
And, next year, if you can afford 16Mb, buy it. You can always convert the
|
|
extra 4Mb into cache on a caching SCSI or IDE controller, or sell it to
|
|
someone.
|
|
|
|
Good luck...

Have you tried out the utility sudo? It allows you to give other certain
|
|
root priviledges.

|
|
: I am trying to set up my system so that others in my family can start
|
|
: and stop it without root privileges. The /etc/passwd I inherited from
|
|
: the Slackware system installation included:
|
|
|
|
: sync::5:0:sync:/sbin:/bin/sync
|
|
: shutdown:*:6:0:shutdown:/sbin:/sbin/shutdown
|
|
: halt:*:7:0:halt:/sbin:/sbin/halt
|
|
|
|
: I suppose I should use shutdown to bring the system down, since it calls
|
|
: halt. When I tried logging in as 'shutdown', I was asked for a password
|
|
: and of course nothing was accepted. I removed the '*' from the entry in
|
|
: /etc/passwd (so no password was needed), then got the message:
|
|
|
|
: shutdown: must be root.
|
|
|
|
: Finally I changed '6' to '0' (so shutdown had the same userid as root),
|
|
: and got a usage message:
|
|
|
|
: Usage: shutdown [-krhnf] time [warning message]
|
|
: -k: don't really shutdown, only warn.
|
|
: -r: reboot after shutdown.
|
|
: -h: halt after shutdown.
|
|
: -n: don't sync before reboot or halt.
|
|
: -f: do a 'fast' reboot.
|
|
: -c: cancel a running shutdown.
|
|
: -t secs: delay between warning and kill signal.
|
|
:
|
|
: I then tried using the entry for halt. When I removed the '*' from its
|
|
: entry in /etc/passwd and tried logging in as 'halt', I got the message:
|
|
|
|
: -halt: can't idle init
|
|
|
|
: Finally, I put this into /etc/inittab:
|
|
|
|
: # What to do at the "Three Finger Salute".
|
|
: ca::ctrlaltdel:/sbin/shutdown -t3 -h now
|
|
|
|
: This means I can't trigger a reboot from the keyboard - I have to
|
|
: actually press the reset button. No big deal.
|
|
|
|
: My instructions to shut down the system are:
|
|
: 1. logout
|
|
: 2. press cntl-alt-del.
|
|
|
|
: My questions for the net:
|
|
: Can you really run shutdown as a login shell?
|
|
: When would you log in as 'halt'?
|
|
: When would you log in as 'sync'?
|
|
: Is my method safe? (filesystem damage, security, etc.)
|
|
: Is there a better way?
