If you are installing a dual-boot system with Win 98 and don't want to
patch your RH 6.2 kernel, you can do this:
Under Win 98, go into Device Manager and under "SCSI Cards" click on
"Properties" for the Promise card. Under tab "Resources", look for the very
first entry for Input/Output range. (On my system it's 1440-1447 but yours
will probably vary.) There will be several I/O range entries but take the
first one in the list.
Reboot with the RH6.2 CD and at the initial prompt "boot:" type in:
linux ide2=0xNNNN
where NNNN is the lower of the I/O range determined above. E.g., in my
case:
linux ide2=0x1440
This will let you install RH 6.2. (The primary IDE port on the Ultra66 card
is ide2 and the HDD plugged into this port will be /dev/hde.)
When you reboot, at the lilo prompt, type in the same thing, e.g.,
linux ide2=0x1440
After you reboot into Linux, add an append line to the Linux section
of /etc/lilo.conf and rerun /sbin/lilo.
Here's my /etc/lilo.conf file:
==========================
boot=/dev/hde
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=dos
image=/boot/vmlinuz-2.2.14-5.0
label=linux
read-only
root=/dev/hde7
append="ide2=0x1440" <=====
other=/dev/hde2
label=dos
============================
(Then you'll need enter only "linux" at the lilo prompt.)
Note: The Linux floppy boot disk won't work. Arrange for a backup means
of booting Linux in case your MBR gets corrupted. I use LOADLIN.EXE
from DOS with the command line:
c:\loadlin\loadlin.exe c:\loadlin\vmlinuz ide2=0x1440 root=/dev/hde7 ro
I found this information on a website, but don't have the URL at hand.

I can vouch for the Linksys device. Worthy of note:
- It's a 4-port 100/100 SWITCH, not just a hub.
- It can do port forwarding, so port 80 on the firewall (the DSL IP address)
can point to port 80 on your Linux box, allowing you to serve from behind
the firewall.
- You can set up a DMZ host that has unfettered access to the 'net, and
vice-versa.
- It supports PPPoE (necessary for running over my el-cheapo PacBell feed;
dynamic IPs suck)
I've had one in place for about a month, and couldn't be happier. I'm
running Firmware 1.22, which had to be downloaded from the website and
installed, no big deal.

You need a lot more than just the /boot partition to get Linux up and
running. Why not just install Linux on your new drive from scratch,
then mount your old drive as the 3rd drive and copy over the files you
need from your old /home directory.

I am a contract instructor at George Washington University. Our
facility manager has to set up a linux machine with a dual processor or
swappable hard drive and neither of us knows how to do this--that is,
what we need and how to implement. She searched for hours for info on
the web but got nowhere. She has good Unix skills, but this is slightly
off her (and my) track. She mentioned getting a Sun Ultrasparc but did
not know what to do after that in configuring a dual processor or
swappable hard drive. Can anyone offer guidance / suggestions?
Especially with urls to any sites online which might offer a one-stop
shop? (I am off to the Sun site after this post to see what they might
have...)

Hi,
Has anyone been able to copy audio CDs with cdrecord and an Acer 8432A
CDRW drive? I'm using RedHat 6.2, cdrecord 1.8-2, and xcdroast
0.96ex-1.
I can copy data CDs OK, but I get a pulstaing noise when I try to copy
audio CDs. I've tried to toggle SWABAUDIO but it has no effect.
Please let me know what to do if it's possible to use this drive.
Otherwise, what drive is known to work copying audio and data best with
cdrecord and xcdroast?
Thanks loads,

Dump the SCSI hard drive, unless you are running a heavy duty file
server there is no reason to waste money on a SCSI drive, get an
IBM75GXP 7200RPM Ultra 66 IDE drive. I just bought the 45GB version for
$265, they run from 15G to 75G. I'm getting 22Mb/sec transfers on the
builtin ATA33 controller on my mother board, the Promise Ultra66
controller can raise that to about 30Mb/second but you should avoid it
until the 2.4 kernel is released, using it with the shipping versions of
Linux is to painfull.

For just a home file-print server etc. you seem to have overspec'ed
the hardware ( not that there's anything wrong with that :-)
You could easily get away with cheaper CPU and network cards. A
celeron 300 or so and any brand name 10/100 NIC (for about $15) would
do the job just as well. And as the other guy mentioned, you don't
really need a SCSI CDROM. And I'd even say you may be better off
with a much larger IDE hard drive rather than an expensive SCSI card
and 9 Gig HD. But since you already HAVE the SCSI disk, and your
chosen MB has a built-in SCSI controller, you could keep the SCSI
and also add a largish ( 20-30 GB) IDE drive using the money you
saved buying a cheaper CPU and NIC. I am stressing on disk space so
much because that's the thing that always runs out first. Specially
if you want to use this as a store for mp3's, video's etc... now or
in the future. You could also buy 2 IDE drives and make a RAID
solution... that may be the best thing you could do to improve I/O
performance actually.
And you're not really going to
waste a huge monitor on the server are you... I didn't think so :-)

YMMV, but I've *always* had issues (serious issues) with machines running
VIA chipsets, including Pentium IIIs running on VIA boards. Also, VIA
chipsets in the past have not gotten along AT ALL with my SoundBlaster Live!
Value (http://paradigm.uor.edu/~harshman/soundblaster); I left those boards
behind for motherboards built on the Intel i440BX chipset, and have never
looked back, so I don't know if the situation was ever resolved. (I do know
that the i440BX is still regarded as a godsend for its stability and
compatibility, especially among the rec.video.desktop crowd, which is always
stressing the limits of their hardware.) Finally, be careful with the eepro
cards (Intel); we've seen TX_TIMEOUT errors on them that have yet to be
resolved. http://www.tux.org/hypermail/linux-eepro100/2000-Jun/0005.html
We ended up going with cards that use the DEC (now Intel) Tulip chipset, not
clones (Kingston, and others).

Subject: SB 16 PCI ? Sound card suggestions. Please.
Date: 7 Jul 2000 02:38:34 GMT
{
I posted this a couple of days ago... no replies yet. So reposting.
with additions:
I've also seen good prices on
1) Creative Ensoniq 128 PCI and some
2) Yamaha Y724 based cards
recently in a local store. Any opinions about these cards.
}
Hi,
I need to buy a couple of good PCI full duplex sound card. The most
important application I'm looking for is telephony. (hence the
importance of full duplex). I don't have much money to spend on
these... about US $40-$50 per card would be the top price I'm
willing to pay (but prefer somthing closer to $30) . SB16 cards seem
to be rather popular also seem to have good support under
linux. I'd prefer that they have good ALSA support of course for
full-duplex as I hear that the free OSS drivers are all half
duplex. (I'm looking for the SB16 PCI card by the way. ISA is not an
option for me)
Some other cards I have under consideration are:
The diamond sonic imapct S100
Some Trident 4Dwave NX/DX based cards ( from brands like Hoontech,
Aztec etc.)
I'm open to suggestions. In fact you could say I'm desperate for
good suggestions as my experience in getting sound working with
linux has not been a good one in the past (and I've been using
linux for more than 5 years!!!). So please please write any
good/bad experiences you have with a particular card.
By the way, another thing I'm looking for is good microphone
input quality as I'd really like to experiment with via-voice
toolkit from IBM. But telephony is the main thing at the moment.
Thanks a lot

Subject: Re: Monitor refresh settings
Date: Thu, 06 Jul 2000 21:53:30 -0600
It sounds like you have two separate issues.
Changing the refresh rate can do PHYSICAL damge to your monitor,
smoke, flames, sparks, that kind of stuff. Make sure your monitor can
handle the rate before you change it. Yes, you can cause the same
problems in windoze too.
You'll probably need to fix the fsck problem before you can do anything
else. I don't know much about those so I will let some else tell you how to
fix that.
After you get it fixed DO NOT reboot normally, when the lilo
prompt comes up press tab (quickly) then type linux 3. The 3 is the
important part, if your selections for linux is called something else just put
a 3 after that, then you will come up in the command line console. If the
display starts to go into graphical mode hit
<ctrl><alt><backspace> (abort Xwindow)
-or-
<ctrl><alt><del> (reboot)
The refresh rate should be in either your /etc/XF86Config or
/etc/X11/XF86Config file, if you're lucky there will be a backup called
XF86Config~ in the same directory.
Try:
ls -l /etc/XF*
-or-
ls -l /etc/X11/XF*
to find the files.
If you have a backup from the date you changed the refresh rate you can
get the old one back by:
mv /etc/XFConfig /etc/XFConfig.afd
mv /etc/XFConfig~ /etc/XFConfig
if the files were in the /etc directory.
If you don have the backup copy you'll probably be best to run the Xwindow
setup program, either XFsetup or XFconfig (not XFConfig), and redo all your
display and mouse settings.

You did not specifiy a price range or what it is to be used for? FYI
you might want to also check out Alphas. Linux runs extremely well on
