This is news to me. What are the symptoms of problems when you try to use

Unfortunately, it's not just a question of getting a SCSI card: the disks
themselves are significantly more expensive. The systems I was comparing
ended up closer to $400 price difference between SCSI and non-SCSI, and when
you're looking at buying several computers, it starts to add up.

Ah-ha. Duplex is indeed a flakey thing under Unix...
In general there's a two-line PCL command you can send before a job to
turn on duplex. There may also be a Postscript method for specifying
this. I always forget what I did with the snippets; you can find them
in dejanews or a good PCL reference.

This depends on what the client apps are. You can install the usual
Windows drivers if they're Windows clients; those will generally allow
you to fiddle with those settings.
For Linux clients, I'm not sure; it depends on your applications.
Dvilj, for example, has duplex mode, papersize, and resolution
options. Dvips has papersize and pk font resolution, but not a true
printer resolution setting. Wordperfect supports all the same drivers
as Wordperfect for DOS, so it can probably control some of those things.
If the application doesn't support it directly, the usual thing is to
have multiple queues, which is where you are now. Most Linux
applications *do* have a simple method for specifying queue, after
all.
If you go with an apsfilter-like naming scheme, it's even more or less
user-friendly. You can name them:
floor1east-1200dpi-duplex-letter
floor1east-1200dpi-simplex-letter
floor1east-1200dpi-duplex-legal
floor1east-1200dpi-simplex-legal
floor1east-600dpi-duplex-letter
...
and just document those names (which may not be necessary if your app
presents users with a printcap-derived list of printers).

Yes, this is true of HP's initial attempts at Linux software, too. As
a rule, printer manufacterers usually produce very poor software.
HP's embedded network stack, for example, predates Linux, and they're
still finding horrid bugs in it. And there are too many examples of
buggy drivers for Windows.
All things being equal, I'd rather they just published proper specs
and left it up to the free software community to write supporting
software.

Well, your critique makes sense, but IMHO the ideal mechanism would
be if it was possible to send "type" information, so that the app could
see if the file "-rf" or the option "-rf" was meant.
I believe this complaint is somewhere in the "UNIX haters handbook".
They complain that it is unwise for unix to allow *any* character
(except for '/') in a file name, because this means that you can create
all kind of "crazy" filenames like "-rf" or even "sh " (note the
trailing space!).
These are often ideal files for crackers to hide all kinds of trojans in.
If "-" signs were forbidden in filenames, this problem would be avoided.
This might have been a possibility in the 70's, but I guess now we're
stuck on this design choice.
(Mmm, this is no good. I guess I'm gonna to write a new OS!)

That's what DOS does.
I find this solution more painful than the unix solution; in unix, at least
the behaviour is consistent.

The shell is an application. It doesn't provide libraries to other programs;
libraries provide themselves to programs.
This particular service is provided by getopt.

Did you try switching slots on the bus? Irq's are often assigned differently
according to card position.
Also, if your bios flavor allows, dedicate the available irq's to the pci bus.

What is the motherboard on your system?
The reason I'm asking this is because older 486 m/b can not handle multiple
PCI bus mastering which many of NIC requires. I had this situation with my
old P60/66 m/b and ended up with upgrading it to a newer socket7 board.
Check your m/b manual and NIC's manual and see if PCI bus mastering is
required.
Good luck.

I have a 486 box (actually an AMD 586 DX4133) that works quite well
with X-Windows. I started out with the same amount of memory and
the same video card you have, and X was painfully slow.

As several people have mentioned, this is your main problem.
I found that going to 16 Mbytes improved performance considerably.
More is better (I'm now at 48).

This is your second problem. Even after I went to 16 Mbytes, the Trident
card was slow, though not unbearably. I have PCI slots on my box, and was
able to get a Diamond Stealth 3D 2000 on closeout. X is now quite snappy;
I notice no delays in X performance, and netscape loads in about 20
seconds or less. The system would be acceptable even if the CPU were
slower (like yours).
If you have PCI slots on the board, get an inexpensive PCI card,
after checking the XFree86 supported list. If you don't try, to find
a better ISA card at a swap meet, etc. Anything except a Cirrus
Logic card would be a step in the right direction.

How did I fail with pnpisatools ? Easily : it doesn't work.
I have a SoundBlaster AWE64, which had been correctly recognised when I first
installed my Red Hat 5.2, yes using isapnp from inside the Red Hat install
process. Two months ago I had major X crashes with EsounD, I'm not sure the
soundcard had been correctly installed BTW. Since then, I've never been able
to get my soundcard properly installed anymore.
"An error occured while opening /dev/whateveryouwant" "device is busy" and
what else ? "You will need to configure it by yourself" I'd be pleased to do
so. But the IRQs and DMAs which were working a couple of weeks ago, don't work
anymore :((
I've been reading and reading again those HowTos, I know them by heart. How
lucky we are, we owners of AWEs, we have a Sound HowTo specifically for us ;)
I tried to paste /etc/conf.modules and /etc/isapnp.conf that I could find here
and there, from AWEs' owners. Whether I add 0xA20 and 0xE20 to
/etc/isapnp.conf makes no difference. I tried to tweak out the RH's
/etc/rc.d/rc.sysinit (which is not a good idea at all, no not at all) in order
to load the needed modules by hand. Last Friday I recompiled the kernel
(2.0.36) for the first time, along with its modules, assuming one of these
could had been corrupted by those crashes. No result.
The best I get, still leave the /dev/sndstat with nothing here :
Installed drivers:
Card config:
...While AFAIK, there should be some references to the Yamaha OPL3 and the
SoundBlaster.
So what ? I gave up. No matter if I can hear weeeak or iuuuup when I open a
window, or not.

Yet another newbie question.
Each day I get a bit closer to 'up and running'. Today's adventure is a

modem and PPP0. Then netuser (sic ?) to dial and connect. I'm certain that
username/password suff is correct and I added my ISPs name server to the
resolv.conf (sic? sorry I believe thats the filename). Netuser dials, modem
connects and then the 'light' on netuser goes green, sort of insinuating
that it was successful. Can't ping the nameserver address though, or, of
course browse anything with netscape. Are there any major pieces I'm

No car analogies! Law 7a clearly states "Car analogies instantly destroy the
thread, as people either (1) start to make ever more convoluted rival
analogies or (2) start to debate cars, especially stick-shift vs.
automatics."

But restricting the keypad to non-numeric characters greatly reduces the power
and flexibility of the design. Why should the candy-machine power-user, who
wants to get his candy quickly, have to restrict himself just so you can avoid
buying a health bar instead of a Snickers?
