Hello,
After building RH6, Mandrake Corporate Server and RH7.1 repeatedly on
my clone box and experiencing endless I/O errors and CD-Rom read
errors (AtaPi resets - the whole game) I decided enough was enough.
Clearly, the CD-ROM was going too fast (now that's a rare complaint in
the newsgroups!!). Or, more accurately, the BIOS settings for the
CD-ROM were putting it in PIO and UDMA modes not appropriate for the
drive.
So, if you are experiencing install failures due to CD-rom read or I/O
problems, look in your BIOS.
I switched my PIO and UDMA settings for the Secondary IDE interface
(on which my CD-ROM is the only device) from AUTO to Mode 0 in each
case.
The result - a perfect, trouble-free install of RH7.1
Now I can experiment with these settings to optimise the interface
without returning to the old problems.
You know - it's soooo nice to give something back!
Have a nice weekend you all.

Take the case cover off and look directly at the modem. If you're
lucky, there will be a bunch of jumpers on the modem for setting the
modem's IRQ and COM port. There also may be a jumper for setting the
modem to "Plug-n-Pray" mode; make sure that is NOT set to PnP. Then set
the IRQ to a free IRQ and the COM to something that won't conflict with
anything you already have installed. Boot Linux and try the following
command:
setserial /dev/ttyS3 irq 9
(That assumes you've set the modem to COM4 and IRQ 9, of course.) If
this doesn't produce any error messages, you're set, just point your
modem dialer (kppp, gnome-ppp, pon) at /dev/ttyS3 and go.
If the modem doesn't have jumpers, you could be in for a rough time.
Look at the modem settings in the Device Mangler of Windoze, write down
what the COM and IRQ are, then try those settings with the setserial
command in Linux. You may also have to use the isapnp and pnpdump
utilities to initialize the card properly (or use kernel 2.4.x with its
new ISA PNP support). Further info is at
http://linuxdoc.org/HOWTO/Modem-HOWTO.html .

Hi Paul-
I don't have objective measures; only subjective at this point. I started
both systems with 2.2.x kernels. I was not terribly happy with the
performance of my 1g athlons at that level. I had stability problems with
lots of X crashes and applications that would cause X to terminate. Since
then I have done a bit of work getting the 2.4.5 kernel optimized, getting
my video card working better, doing things like enabling mtrr support and
using hdparm to further tune things. I am very satisfied on both athlon
systems now with performance.
At the beginning it seemed that the keyboard buffer would overflow and the
hard disk led would light up with simple copies. I also could not manage to
do simple things at one time under a 2.2 kernel. I went first to 2.4.4 then
on to 2.4.5 and started reading a bit about hdparm, dma access for my Maxtor
drives, mtrr support, getting nvidia agp enabled or the kernel agp driver,
etc. So now I feel I have reached a rather good point with the athlons I
use. They are very responsive and I believe that by testing with hdparm,
getting kernels recompiled to maximize the athlon (which I believe helps), I
have not seen any of the 2.2 series crashes or bus errors.
Simply tuning the hard disk using hdparm made a recognizable difference.
Doing things like using the latest nvidia drivers and getting agp enabled
helped. Its been a learning experience but I am very happy with everything
from playing descent to doing word processing to some quaking. If you want
to see some baseline performance changes, try running hdparm against the
disk and see what you get now in disk and buffer action. Next read this
http://linux.oreillynet.com/pub/a/linux/2000/06/29/hdparm.html and notice
how the disk systems got better with each hdparm change. There are some
cautionary notes regarding dma and I noticed on a second system that dma was
a tricky business. On my twin maxtor drives, I get pretty significant speed
increases; much like what is reported here.
I also agree that a combination of processor, video card, and memory do not
hurt; but also if you spend a bit of time looking at variousu tuning options
for the hardware, I believe you can see significant, albiet subjective,
performance increases.
The athlon series to me represent a good quality solution which I can
effectively tune up with things like hdparm, new 2.4 kernels, better X, etc.
The price point makes them even more attractive. For less than $500 US I
get a barebones system that all I add is a cd player. I happen to have lots
of this kind of stuff laying around.

?? The 25-pin SCSI connector is a perversion of the SCSI standard
created by removing most of the ground wires from the 50-pin narrow-SCSI
connector. I don't think you can buy a card with a 25-pin connector new
these days. You can, however, buy a 50-to-25 pin adapter and use that.

Get a Linux-supported card with a standard 50-pin narrow-SCSI external
connector, then get a 50-to-25 adapter. Symbios makes a number of cards
that should work for light duty.

I think it's unlikely you will be able to recover the information, but
if you're willing to try, copy the information from hda2 to a file, run
dosfsck on the file, and then try to mount the file via loopback. Like
so:
dd if=/dev/hda2 of=/path/to/somewhere bs=16k
dosfsck -a /path/to/somewhere
( many error messages will appear...)
mount -t vfat /path/to/somewhere /mnt/mountpoint -o loop,ro
Also, your partition table is seriously messed up. Take a look at it
again, and notice the following things:
0. hda2 overlaps with hda1. Partitions should *NEVER* overlap. That's a
recipe for certain data loss.
1. hda2 is of type Win95 Extended, but it doesn't contain any logical
partitions. hda5 is supposed to be the first logical partition, but it
is not contained within hda2.
2. The cylinder start+end on hda5 are completely bogus. Especially
since a FAT16 partition cannot be larger than 2G.
There's a utility called "gpart" that can attempt to fix this problem.
Check http://home.pages.de/~michab/gpart/ . Also, go to
http://freshmeat.net/ and see if you can find anything useful by
searching on the keyword "partition".
And whatever you did to cause this, don't do it again. Mangled
partition tables are *NOT* fun to fix, as you will find out....

Sure you can by new scsi adapters with 25-pin connectors. The adpatec 2906
which uses the standard aic7xxx driver is an example of one such.

XCDRoast's error handling leaves a lot to be desired. Bring up an
xterm/eterm/konsole and execute "cdrecord -scanbus", and if you don't
get an error message, execute "cdrecord dev=X,Y,Z speed=W file.iso"
where X, Y, and Z are the numbers corresponding to the CD-RW that
cdrecord -scanbus picked up, and W is the speed you wish to burn at, and
file.iso is the ISO image you made with mkisofs.
cdrecord's error messages are at least more verbose than XCDRoast's,
which will give us more to go on.

Hello,
I just recently installed Red Hat Linux 7.1 on a 8 GB partition with Win98

not seem to recognize my ethernet adapter (the chipset is an ADMtek AN986).
The adapter works fine with Win98. Farallon does not provide any support
for Linux. Is this a Plug-and-Play problem (I haven't found a utility to
change this)? The Ethernet HOW-TO has not helped.
Thanks.
