I also found (when I was using redhat 5.x) that upgrading to the most
recent 2.0.x kernel (2.0.36 at the time) had it detect all the memory.
You might want to try upgrading to 2.0.37 (the most recent 2.0.x kernel)
and see if that helps.

It seems that adaptec may have changed up some of the bios/control
chips. I have contacted the maintainer of the AIC7xxx driver and he is
going to let me know if it is going to be aproblem or not.

=============================================
Re from Niels
C'T Magazine ( best magazine in the world) dutch edition tested
the adaptec 2930 card and found out that Adaptec has assigned a new Device
ID to the 2930 -> 0011h. The 2940U2W has Device ID -> 0010h. That's why the
drivermodule aic7XXX can't recognise the card altough they use the same
controller (AIC-7890AB) and Bridge (AIC-3860).
C'T DID test the card. They used a patch in
quote"/usr/src/linux/include/linux/pci.h"
Then just recompile the aic7XXX module and it uses the 2930 as it were an
2940. Easy huh! Now... As I stated before I'm a Linux newbie and don't know
X11 from an X-file(sorta) and I don't know how to "just recompile the
AIC7XXX module". Just bought Linux for Dummies and I will find out I
guess...
Hope someone who has a few more braincells can use this information <<ALL

Subject: ADSL versus Cable modem.
Date: Tue, 29 Jun 1999 11:36:08 -0400
An article in our local newspaper announced that the phone company (Bell
South)
had begun offering ADSL service and that the cable company (Time Warner)
would be offering Cable modem service within the next few months. The
article
claimed that download speeds would be about the same but uploads via Cable
modem would be somewhat faster. In both cases the company would come and
install the required modem.
Because of the way things seem to be nowadays, I assume both companies
will be supporting operation only under MS Windows and that I'll be on my
own
if I want to use Linux.
What kind of questions will I need to ask to insure that whatever service I
go with
will be compatible with Linux? Are there "Winmodems" for Cable and/or
ADSL?
Any pros and cons? (ADSL looks like it will be more expensive).

Same thing happened to me. I managed to find some help, and the

ckraid --force-check --fix /dev/md0
raidadd /dev/md0
raidrun /dev/md0
Then, I was told to mount it, and I did, but it may not be necessary.
Then I rebooted and everything went fine.
I noticed that the --force-check option was not in the man page, but
did show up when you do "ckraid --help". By the way, I also made
a backup before I did this.

Hi there,
YOu need the **exact** horizontal and vertical sync rate for the monitor.
Look in your monitor manual. I had similar problems. The current version

Absolutely, but I'm not sure it's the fault of the controllers, but rather
the drives. I used to have my PCI bus clocked at 41.6MHz (83.3MHz system
bus), and everything worked hunky-dory with my old Western Digital Caviar
drive. Then, I bought a Maxtor Diamond Max+ and it didn't like it - I
presume the DSP hardware on the drive couldn't keep up, because I got really
severe retry problems, and a throughput of about 12k/sec. :-( It wouldn't
even work at 37.5MHz (75 MHz system bus). Maybe Intel have a hand in
this.... (I can feel a conspiracy theory coming on <g>)

As I understand it, the G400 is not directly supported yet in X. However,
you should be able to get it running with the SVGA X server, or the
frame-buffer X server if you compile in VESA frame-buffer support into the
Linux kernel. What you won't get is any graphics acceleration, so it could
be quite slow under X, although it should still be perfectly usable. I
suspect the G400 will be supported directly quite soon, though, as the
underlying architecture isn't too dissimilar to the G200, which already has
good accelerated support, and Matrox cards seem to be quite popular with the
XFree86 programmers.

thanks for the clarification.
so, to make sure I got everything straight,
Ultra DMA is byte wide (in 33 and 66 mhz versions)
and PCI is 4 byte wide (in 33 and 66 mhz versions)
EIDE drives use Ultra DMA to send/recieve data
to/from the controller card.
so, does anything use the PCI66 interface?

The Internet is a shared bandwidth system. Meaning that you get high
peak rates, while paying for low average rates. That's the whole point
of packet switched networks. One that the telephone companies, with
their guaranteed bandwidth, switched circuit mindset have had trouble
coming to grips with.
Packet switching allows a large number of users with sporadic traffic to
share higher bandwidth than any individual user could afford. The
closer you can get the shared part to the user, the better it works.
After you have aggregated a sufficient number of users together, the
traffic starts to level out, and a constant bandwidth connection makes
more sense. Ironically, ADSL puts the guaranteed bandwidth part near
the user, where it is not cost effective, and then combines users into a
shared pipe to the Internet, where guaranteed bandwidth would work
better.
Another way of phrasing the previous post is that during peak times,
ADSL and Cable both provide their minimum bandwidth, whatever that may
be. During off-peak times, ADSL continues to provide the same minimum
bandwidth, and Cable provides its maximum bandwidth.
A guaranteed minimum bandwidth is a good thing, and worth comparing.
Setting the maximum to be equal to the minimum is not a benefit, but
that's what happens when you don't have shared bandwidth.

Most likely they will not support linux. But that should be no problem,
since both cable and ADSL use ordinary
network cards as interface to your computer. So, just read the FAQ's
about Networking and DHCP and you should be able to set up your
connection yourself. If in doubt or trouble, i'm sure you will find some
help here.
The biggest con for cable is the fact that you share the bandwidth with
every other person on your segment. Put it simply: 1 user gets
(theoretically) the full 10Mbps, 10 users at the same time only get 1
Mbps.
Now, I use cable for a bit more than 1 year and I have no speed-problems
whatsoever. When i download something that is mirrored at my provider's
computer, i get speeds in excess of 500 Kbps, which means even megabytes
are transferred in a matter of tens of seconds. On the other hand,
downloading something 'on the internet' greatly depends on the speed of
the route to the host. And here the basic rule applies: don't try to
download at the busiest moment of the day.
I have no experience with ADSL, so no comments on that from me.

I'm not so sure about this, though I haven't tried to get mine to work
yet. Look at this entry from linux/drivers/scsi/ChangeLog:

and there is a kernel config option to enable 53c400 extensions on the
5380 driver, and in Documentation/kernel-parameters.txt there is an
option "ncr53c400a= [HW,SCSI]". Also, in NCR5380.c around 1996:

Also take a look at README.g_NCR5380 and the *NCR5380.* source files.
