Check to make sure that you haven't got an option that looks like
"Memory hole at 15-16MB". Linux expects RAM to be contiguous.

Is it a Vortex or a Vortex 2? OSS has a barely-usable V2 driver that
you have to pay money for. Just buy a new sound card.

You have to keep LILO, or you won't be able to start Linux. Do things
the way you probably are now, just set the timeout for LILO to zero.
(Actually, some very small, nonzero value might be better, so you can
interrupt and specify kernel options.)

Subject: Re: Kernel question
Date: Mon, 11 Sep 2000 19:15:50 GMT
Where does the server hang on bootup? Are you able to complete the
boot process if you use the boot disk created during the install?
Have you considered creating a new ISO image with the 2.2.16-3 kernel?
You could also download a new ISO distro and burn it onto a cdrom.
Another option is setting up Redhat Kickstart with the distrubution on
another server.
A quick work-around is also possible with a boot disk to avoid the
RAID issue until you have the newer kernel installed.
If you don't have a cd burner, you could also do an install direct
from a drive partition by copying the distribution to a partition on
the target boot harddrive.
All of these options are explained on the Redhat Install Support
website. Sometimes it helps to have someone tell you that other
options actually exist.

Date: Mon, 11 Sep 2000 19:23:34 +0000
Hello,
I'm trying to setup a dual processor system with an ultra66 promise
controller. A friend of mine told me I had to put the controller in one
of the slots, boot into my RedHat linux 6.1 installation disk, and
select another terminal to look at /proc/pci. What I get for the
promise controller section is this:
Medium devsel. IRQ 11. Master Capable. Latency=64.
I/O at 0xeff0 [0xeff1].
I/O at 0xefe4 [0xefe5].
I/O at 0xefa8 [0xefa9].
I/O at 0xefe0 [0xefe1].
I/O at 0xef00 [0xef01].
I'm new at this, and he told me to use the RedHat 6.2 bootnet.img (with
promise controller support) and to enter
text ide2=0xeff0,0xefe4
at the boot prompt, taking the addresses from the first two entries
above. I've done this, but whenever I try to boot (with my freshly made
boot disk) after the install is finished, I get a kernel panic, can't
mount root.
Any help would be greatly appreciated.
Ken

Thanks. I'll triple check, but I never set this option. I'm assuming that
you're referring to the CMOS settings in the BIOS here, not some Linux
config file.

Vortex 2, I think. Like I said before Diamond has the crappiest support of
all companies I've ever seen, followed closely by Logitech. Any suggestions
for soundcards? I've got some ISA cards kicking around here. No sense
keeping the MX300 if niether OS can make use of it's features.

Okay, I did more extensive testing last night, and as I scanned several
webpages I came across something about downloading (FTP) a file twice would
put it in the cache, and then a second download would show higher speeds. I
tested this (after taking the webpage for granted at first) and got 9meg/s
download on the second run (still only 2meg/s the first run). This is
tested on a 15meg file, not the biggest file to test, but still should be
alot faster than 2megs. This leads me to believe that it must be the way
Linux is handleing the file system calls, or the like. Can this be
optimized? I always put Linux way above anything microsoft in the OS realm,
and I'm sure there's a fix for this. The processor of the Linux box is a
300mhz K6-2. I watched the CPU load during transfer and it did get up to
50%ish, but thats not bottleneck speeds. So I think my original assumption
was inocorrect, not the ethernet card itself, but the filesystem. Also, I
have only tested downloading from Linux=>windows .. was more assuming upload
would be the same, but in the light of what I have learned recently, that
could be false also. Thanks for any help.

I suspect you are hitting a limit due to unoptimized disk I/O. See
"man hdparm".

Part of the reason it's slow is that you've put more RAM on the board than
the chipset will cache. With an i430TX/VX chipset, you really should use no
more than 64MB.

With the amount of RAM you want to run, about the only processors that would
sidestep the chipset's cache limitation would be an AMD K6-III (discontinued
and very hard to find, though 350s are popping up now at OK prices) or
K6-III+ (also hard to find as AMD only makes those for OEMs to install in
notebooks). At this point, you might as well build a whole new computer
around a Duron or Athlon, with the appropriate motherboard, memory, etc.
You could move drives and other stuff from the old computer to the new one,
but since they're probably just as behind the times as the processor and
motherboard, your best bet would be to keep your old computer whole and use
it for stuff that doesn't demand as much performance as today's apps need.
Get enough old computers together and you could even think of making your
own Beowulf cluster. :-)

Subject: Logitech wireless keyboard and mouse
Date: Mon, 11 Sep 2000 12:16:24 -0700
Reply-To: [EMAIL PROTECTED]
I recently installed a Logitech Cordless Desktop Pro on my system here
at work. It is an Epox EP-61BXA-M motherboard with a 450 MHz
Pentium II. I'm running RH Linux 6.0 and Gnome desktop.
By just swapping in the new hardware, I got a basic system that seemed
to work OK. But occationally the mouse pointer would take off on its own
and send random button clicks to the system. It also did not use the wheel
capability or the side button on the wireless Mouseman +.
At this point I started my quest into the man pages and news groups to make
things right. Since I got so much information from this group, I thought I'd
share my solution in the hope that someone else could use it. I'll go through
all the steps I took just in case one of them works for you.
The best info came from this site:
http://www-sop.inria.fr/koala/colas/mouse-wheel-scroll/
I did everything recommended here and things worked pretty well, but....
My original configuration had a PS/2 keyboard and Logitech 3 button mouse
in a PS/2 port. A direct swap of hardware had the keyboard working
perfectly, but the mouse only used three buttons. Button 1 was left, button 2
was a press on the wheel, and button 3 was right. Not bad, but the fourth
button on the side was not used, and the wheel was not used. Switching
the protocol parameter from "PS/2" to "IMPS/2" made the 4th button act
like button 2. Not bad, since the wheel press has a pretty strong spring. Adding
ZAxisMapping 4 5 to the pointer section of XF86Config added the wheel
function, but lost button 4. Changing to protocol "MouseManPlusPS/2" allowed
using xmodmap to restore button 4 to button 2. But the mouse would still
go postal occationally in all the PS/2 modes.
Time to move the mouse to a serial port. Just change the /dev/mouse link
from ps2aux to ttyS0 and set the proper permisions. That immediately and
permanently fixed the erratic mouse problem, but there is no "MouseManPlus"
protocol for the serial port. The closest is the "Intellimouse" protocol. This works
great if you don't want to use the side button. But to get the side button to work
as button 2 I had to do the following:
1. Put the following lines in XF86Config:
Buttons 6
ZAxisMapping 2 5
2. Create a .Xmodmap file at /usr/X11R6/lib/X11/xinit/.Xmodmap or ~/.Xmodmap
with the following line:
pointer = 1 4 3 2 5 6
3. In the Gnome control center -> Session manager -> non session managed Startup
section I added the line:
xmodmap /usr/X11R6/lib/X11/xinit/.Xmodmap
What does this do? First we tell XFree86 that the mouse has 6 buttons including wheel
up and wheel down. Then map the wheel to button 2 an 5. That has the effect of
loosing
the wheel press button, but since X only recognizes 5 buttons, you have to give up
something. Adding the pointer line to the .Xmodmap file tells X to remap button 2
(wheel
down) to button 4 which all the apps use for wheel down and map button 4, the side
button
to button 2 (the way I like it). You can put the .Xmodmap either globally or locally
and xinit
will find it. However, gnome apparently reruns its own xmodmap pointer and screws this
up. So in Gnome we need to run it again at gnome statrup.
Of course the proper solution would be to fix the PS/2 functionality in XF86 or to add
MouseManPlus capability to the serial drivers, but that's beyond anything I wanted to
mess with. Hope this helps some of you out there.

I think you nailed it .. the "Buffered disk read test" benchmark was maxing
at about 2.3meg/sec which was what I was downloading at. Unfortunately by
messing with options I've only got it up to 2.67meg/sec ... I think I need
to recompile kernel to support ultradma, think that will dramatically
improve performance? Also, when i formated the drive I just did "mke2fs
/dev/hdc1" .. so I guess it did the default 1024 block size ... somewhere I
read reformatting it with 4096 will improve performance by reducing number
of seeks? Anyone know how accurate that is, it will require alot of file
moving to get that reformated. Thanks again.

2.2.17 checks out OK using the 2.2.14 ppp.o module--I just tested it.
I also heard a rumor that IBM is working with (for/independent of?)
lucent to build a modem driver for the 2.4 kernels. The ppp setup has
changed with the kernel 2.4 (apparently, pppasync and ppp now use a
common module called ppp_generic, and have been consequently renamed to
ppp_sync and ppp_async or something similar), so I have doubts about the
2.2.14 ppp module working with it.
