Hi, just want to find out if anyone has installed RH7.0 on an ASUS K7V133A
mboard, and would like to know of your opinion of such a combination.
Thanks in advance.

I'm hoping that NetGear picks up the drivers and posts them as well. I've
got two PA301 cards standing between me and networking with Linux.

Anybody have an idea if a Netgear PA101 would work? It's a USB version of
the adapter. The PA301 is PCI.

Xactly! It makes me instantly ill, though I can actually see
the flicker. Like I said in an employee/manager metting I
had to tell my boss to turn the thing away or I was afraid
I'd mess up all her pretty papers. She had no concept,
though was pleasantly surprised when I tweaked her system.

Safe mode? You still using toys? WinNT and Win2K will
allow changing the video mode without re-booting. I thought
Win98 would too, but I don't do toys (not that I consider
anything from M$ much above a toy).

Send 'em back! 85Hz should be easy with today's cards. I'm
using a Matrox Mystique B/220 here at 1280x1024@85Hz. THis
is a two-year old IBM G94 (a damned good one). This antique
hardware works quite well.

It's not subtle to me! Sometimes I wish it were, but to see
people wasting good hardware (IBM P260s - 21" professional
monitors) at 1024x768 makes me wanna cry.

I was wondering if anyone knows if Red Hat supports the 815 chipset?
I can install RH 7.0 but then get no networking at all.
Any thoughts on what could be causing this problem? thoughts on a
possible solution? Thank you.

One small point - some people don't use their serial ports at all,
and intentionally disable them for the IRQs. That could be a good reason for
not using serial anything.

?? Careful there. Benchmarks lie, and hdparm is *NOT* a reliable
benchmark for this sort of thing. bonnie++ is better. A good IDE
system will never beat a good SCSI system wrt multi-user/multi-process
performance. Get a 4-disk SCSI RAID and a 4-disk IDE RAID, then have
many users hammer on each one and see which performs better.

I would guess that 35M/sec is pretty close to the maximum rate at which
your Head-Disk Assembly can pull data off the platters and deliver it to
the controller. This rate is mainly dependent on two things: The
density of data on the platters (bigger drives = higher bit density =
faster disks) and the rotational speed of the platters (10000 RPM faster
than 7200 RPM).
UDMA/{66,100} is a marketing gimmick and/or planning for the future,
since current hard-drive technology can't feed data to the controller
fast enough to saturate a UDMA/66 bus. Wait 6-12 months and this will
change. If you need faster throughput than 35M/s, which is pretty damn
fast, then consider RAID-0 and/or SCSI.

"KVM" refers to a device that allows you to control more than one
computer with only one set of (keyboard, mouse, monitor). Except that
won't help you since you want to have 2 or more keyboards attached to
one computer and have some way of switching between the keyboards.
(Dammit, I must read posts more carefully...)
I can't help thinking that this is a relatively uncommon case. See what
you can find with a search on "switchbox"?

100MHz is nothing for a monitor. Many business/engineering
applications demand much higher resolution and refresh
rates. At work I'm running 3200x1200 on a dual display. I
could easily use more.
This system runs 1280x1024@85Hz. I do have a 19" monitor,
but was running at 1024x768@85Hz at home on a 15" display
five years ago.
> Time to go for lcd flatscreens.
Err, my primary display at work *is* a flatscreen. It's
part of my ThinkPad A21p and runs at 1600x1200 (15"
display). I have the ThinkPad sitting next to a P200 also
running at 1600x1200 as the secondary display. That's the
proplem. The P200 doesn't go above 75Hz at 1600x1200. It's
driving me nuts, though the solution seems to be turning off
the lights for the (entire?) floor during the day. I'm not
the only one with this problem.

According to a number of posts on various sites (see below the post URL's) it
would appear that your 815EEA network LAN is capable of using a eepro100
module to get itself initialised. As a result, you may have to put an entry
into your modules.conf file the line:
alias eth0 eepro100
Additionally, you might like to check inside your BIOS and make sure that the
following options have been set:
* PnP Operating System: No -----> Normally it is Yes
* USB Legacy/Support: No -------> Normally it is Yes
Here are some URL's which have discussed the problem:
