Subject: Why can't I use on board IDE and a Promise Ultra66 at the same time?
Date: Thu, 06 Jul 2000 19:24:40 -0400
Here is what I'm trying to do. I have two drives, an IBM 14.4G ATA33
drive and a new IBM75GXP 45G ultra 66 drive. The 14.4 has the OS on it,
the 45G is application and user space. I want to boot from the 14.4
connected to the onboard controller while using the Promise card for the
45G drive. Unfortunately the BIOS seems to ignore the onboard controller
if there is a device attached to the Promise card. I don't want to
attach both drives to the Promise card until Redhat provides a standard
kernel that will boot off of the Promise card. I use Win4Lin so I can't
build a custom kernel unless I'd be willing to go back to rebooting my
system into real Windows, a prospect to horrible to contemplate. Has
anyone been able to boot a setup like this.
The system is a Dell Dimension R450 with the A13 BIOS.
Thanks,
Josh

If only :-)
no, it will just let you see whether the prograsms are
there, or on your PATH so you can run them. Clicking
things usually means that error messages aren't visible
(they'll probably be on the console though) on the
desktop. Doing it from the command line means you'll see
any error messages in that terminal window.

Subject: Touchpad mouse problems
Date: 6 Jul 2000 23:11:33 GMT
Reply-To: [EMAIL PROTECTED]
I have been using a refurbished NEC 2430CD notebook for the last
eighteen months where I've installed Windows 95 and Slackware
Linux 3.1 (kernel 2.0.27) on the hard disk.
Up to now, I have not had any problems with the hardware (mouse,
keyboard, screen, PCMCIA slots). Recently, I've encountered problems with
the touchpad mouse (which comes with the usual two L/R buttons). The
problems are of the following nature under Linux's fvwm X window manager:
(1) Sliding my finger with the touchpad mouse from one xterm
window to the next xterm window selects text, instead of just
"moving" from one window to the next. This effect is independent
of how hard I press my finger on the touchpad mouse.
(2) Left-click button is completely disabled.
(3) Right-click button seems to become the left-click button, and
(4) pressing Left and Right buttons simultaneously no longer works
to give the Middle button functions under X.
These problems exhibit similar characteristics while I'm in
* DOS - I get stuck using 'edit', or
* Windows 95 - "sliding"/button functions seem mismapped
The curious aspect to all of this is that I had no "warning."
One evening, all worked fine, and the next day, I've got "instant"
touchpad problems.
I tried installing a 3-button ChampMouse onto the PS/2 port
and things seem to work fine with the "external" PS/2 mouse.
In fact, it appears that both the touchpad mouse and the
"external" mouse are functional.
However, a problem arises if I accidentally touch the touchpad mouse.
I get the same kinds of problems I discussed above and I can not
get any reasonable mouse (proper click or select) functions with
the external PS/2 mouse. In other words, I get "stuck" and have
to (soft-)reboot, which is a real pain in the butt.
So, I'd like to find some way of disabling the touchpad mouse
on both the Win95 and the Linux sides and just use the
external PS/2 mouse.
I'd appreciate any help/comments about this.
Thanks.

Nancy,
Try configuring the switch port of your firewall to 10
Mb/Halfduplex. We have numerous problems getting our Cisco 5500
switches to autosense. It seems it has something to do with the
cable length. In our lab, autosensing worked 100% of the time.
Cable lengths were short, < 10 m. In the field, where the cables are
around 60 m, we have seen negotiation problems with several different
NICs (3Com and others). You may also try set port disable/set port
enable. This for some reason has always brought the port back online
(w/autonegotiation). But failures still occasionally occur (when the
users reboot), unless we force the switch to the correct speed and
duplex. Duplex is extremely difficult to autonegotiate. The 3c503,
AFAIK, is a 10 Mb/s half duplex card.

OK, so I saw that somebody else had this same card and also could not get
it recognized by RedHat...
Here is how I got it to work:
I made a DOS floppy and booted up the linux box with that, then stuck
in the install diskette that SMC had bundled. I ran the configuration EXE
(SMCINSTALL.exe or something like that...) and used "custom setup" to turn
plug and play off. Then I began to reinstall RedHat 5.2...
Although the website said that you can use the SMC Ultra driver, it still
would not recognize until for no apparent reason I tried using the NE2000
driver... jackpot. it took and set up just fine.
Now I just have to configure TCP/IP...

Redhat 5.2 is ancient, upgrade to 6.2 which has Gnome included. It's
relatively easy to attach an icon to a launcher, although it's still a
little kludgy in a Windows 3.1 kind of way, it's not automatic the way
it is in a Mac or the way it seems to by in Windows 98.

Date: Fri, 07 Jul 2000 00:37:28 GMT
Hello Linux experts. I'm a novice who wants to network my home,
but wants to avoid purchasing NT Server, for lots of reasons.
My goal: Linux home server for three or four PC's, for sharing
files, printers, and cable modem internet connection.
Just need bare essentials for a server, and want to be sure
everything is 100% guaranteed to work with Linux (Red Hat,
probably).
Here's the configuration I'm planning; PLEASE let me know if
anything below might give me Linux-compatibility problems...
============================================================
Group 1: planned hardware I don't own yet:
Motherboard: ASUS P2B w/ onboard Adaptec SCSI controller
CPU: Intel P-III ~500MHz
NIC: 3COM 10/100
Cable, RJ-45 twisted pair (specs?)
Graphics card: ? (suggestions please)
SCSI CD-ROM drive: ? (suggestions please)
============================================================
Group 2: hardware I already own:
Hard drive: Seagate Barracuda, Ultra-2 SCSI, 9G
Monitor: ViewSonic 17"
Printer1: LaserJet 5
Printer2: Phaser 740
Logitech keyboard, trackball
...oh yeah; I also own:
screwdriver; pliers; fire extinguisher; sledgehammer :-)

I would appreciate watch-outs, suggestions, and warnings. Also,
advice on anything I might have overlooked. Thanks a lot.

Have you tried to mention this opinion to synthesis tool vendors as

I have seen several, very small distributions of Linux available on the
Internet.
If you go to http://www.linux.org you will find a link that say's
"Distributions".
Click on that link, and it will give you a Web page that has a section that
say's "Distribution Information", with a few links under it.
Click on those links and you will find MANY different distributions of
Linux.
While it is true there is MUCH HYPE over Red Hat Linux being a good, (IT IS
a very good distribution don't misunderstand me) if your going for small &
efficient, an "OFF THE SHELF" distribution probably won't work for you.
If your really pressed for space (12 MB is pressed for space, but more than
enough for a Linux install), and your looking to do an EMBEDDED system, then
you would probably be better off just creating a custom installation for
your project, with only the things you really need.
If you need assistance you're welcome to email me, or post to the newsgroup
as well.
It's only my opinion, and I welcome any comments or suggestions from anyone,
but I hope it helps at least.

No problems with HW. Nice MB. I've got a slightly dated P2B-D (dual CPU
version, dual P-II/400's in it). For a server you might even want to
consider a Celeron or K6-2. On a different server I just upgraded the AT
MB to an old ASUS P5A-B with a 500MHz K6-2. Very nice and cheap little
screamer.
One thing that I may point out is that my main server is a heavier-duty
machine running an Oracle database. The smaller server is closer to what
you'd want on a home network.
Personally I've had zero problems with 3COM, to the point that I'll pay
a little more for the peace of mind. Same with ASUS MBs in general.
> Graphics card: ? (suggestions please)
For a dedicated server that you kick under the table and forget about?
You can you an old 16-colour 256k RAM VGA card and ssh into the server
if you really need to do anything.
If you intend to sit at the KB and bash on the machine directly, I've
had good results with ATI and Matrox, not to exclude other good cards.
> SCSI CD-ROM drive: ? (suggestions please)
You can get by fine with a cheap IDE CD-ROM with this MB. My P2B-D works
great with three SCSI HD configured for RAID-5 and a IDE CD-ROM drive.
My two cents.
