You can mount your Windows partition directly into your Linux tree and
manipulate the files there (almost) exactly like they were native to
Linux. (I say "almost" because Windows doesn't have the ownership and
protections scheme that Linux does, so Linux has to fake them.)
Here's a sample line from my /etc/fstab (from before I deleted my Windows
partition). It assumes Windows is on partition 1 of my primary drive
(thus hda1), mounts it to show up as the /host-for-c directory under
Linux, and makes it owned by the user and group with id=500, namely me:
/dev/hda1 /host-for-c vfat
user,exec,dev,suid,rw,uid=500,gid=500
You'll need to manually create the mount point (directory) before the
first time you try to mount it. The 'vfat' means it interprets Windows'
faked long file names. Add noauto to the list of properties if you don't
want it mounted automatically whenever you boot. Use 'man fstab' to get
more info.
The above was for Windows 95, but I'm not aware of any relevant changes to
Windows 98.

It doesn't matter. Let space and available partitions be your guide. If your
disk is nearly full, or if it is all on one partition and you don't have a
reliable way to back it up before you try to split it into multiple
partitions, then a second disk is the way to go. Otherwise it isn't
necessary.
Once you've picked a distribution to install, find a copy of its installation
guide and search it for suggestions about how to spread Linux over several
partitions, and how large the partition(s) need to be.
Good luck,

I had one temporarily, and I got the 2D part working on short order, though
admittedly I've had a fair amount of experience with Linux video
configuration.
I didn't keep it long enough to attempt the 3D setup, so for all I know that

Well, I can help yah out here. I bought first an ide burner. If your
gonna go the inexpensive route (hope not) then you will have to
recompile your kernel and turn OFF atapi support then turn ON scsi
emulation. However, IDE is gonna be slow and will most likely tie up
your system because of buffer underruns.
My second cdburner was a scsi [yamaha 4416s 4x scsi] and the performance
boost alone was great. The important thing is to get a large buffer. My
yamaha has a 2 meg buffer so that I can burn in the background pretty
much and not risk a coaster.
Even though you will pay more, Its worth it to go scsi in every device.
Specially since you already have the controller installed.

IT should be possible to get it to run in the configuration
you have it but I'll tell you what *I* did and how I got my
system working. You can take it from there.
I have a dual-channel IDE controller built into the
motherboard. The master on the primary channel is my boot
drive (Linux/NT - Linux mostly). I have an ATAPI 40x CDROM
as the slave on the primary channel.
A little while later I decided to add a CDRW drive. I chose
an HP 8100i IDE. I put it as the master on the secondary
channel. I then got fancy and put a 4G IDE as a slave on
the secondary channel.
You'll have to recompile your kernel (2.2.x or greater) to
include IDE SCSI Emulation. As a boot option I have
"hdc=ide-scsi" which tells Linux that HDC (the HP8100i
master on the secondary IDE channel) is to be treated as a
SCSI device.
cdrecord, mkiofs and xcdroast are the programs I use to burn
audio and data CDs. Read the CDRW HOWTO - it's very good
and will explain in detail what needs to be done.

Hello, Harald. My Agfa Snapsacn has never worked with the 2.2.x kernels.
It stopped working as soon as I upgraded from 2.0.x.
I am interested in the new Snapscan backend. I am using a Debian
package of Sane 1.0.1-3. By itself, this most certainly doesn't work
with my Snapscan. Only the replacement of the gs.c and sg.h files get it
working.
How would I change the Snapscan backend? How do I tell which version I
already have?
Thanks for your help.

For compiles you should get something very close to a 100%

Subject: Configure OLITEC PCI 56K V2 Data,Fax Modem
Date: Thu, 22 Jul 1999 22:56:29 +0200
Hi,
I failed to configure my modem with Redhat 5.2 :
1) I tried the setserial command to force parameters to the values I found
in my Win98 environment (I know it is a poor reference) but minicom cannot
even have it dial. It is supposed to be on COM3/cua2.
2) The Olitec doc suggests a wrong port assignment for dialing problems. I
tried to play between cua2 and cua3 w/o success.
As I read through this newsgroup, I saw the "winmodem" term that makes me
wonder if my modem can be used at all under Linux.
Any clue welcome. Merci beaucoup!

Try doing a mount -t iso9660 /dev/cdrom /mnt/cdrom It may
not be mandatory to put the whole command line in - the
cdrom is normally listed in fstab - but it's a good place to
start the troubleshooting process.

You're pretty close - you DON'T want to disable the
IDE/CDROM but you DO want to compile in IDE-SCSI emulation.
I have an "hdc=ide-scsi" as a boot option and my system (HP
8110 ATAPI CDRW) works great.
The software you'll want to get is xcdroast, cdrecord and
mkiofs (the last two come budled with xcdroast). This is
all you'll need to burn some CDs. There are several other
CDRW related packages, xcdroast happens to be the one I use
most.
Of course, check the HOWTO - it's very good.

Sendmail does not support attachments per se. You will need something to
do the attachment encoding in whatever format you want to use (MIME
being the modern standard). There are a number of freeware/GPL Unix
toolkits to do this,
Of course, if you dump that old fashioned CGI stuff and use Java

How much memory are you showing available to the machine if you run top?
If your machine is swapping out to the hard drives because it thinks it's
out of memory, the problem ain't the RAID, it's Linux not seeing all its
memory.

I tried to use kdat to do a backup tonight as it's been far too long since
I did one. I think kdat is seriously broken; it saw my that I had a tape in
the drive (Connor CTMS 3200) once and asked to format it. I let it format the
tape; after that, kdat insisted there was no tape in the drive.
Strikes me that you'd want your backup utility to be as reliable a piece of
software as you've got on your system. Even if you could get kdat to make
a backup, I don't think I'd trust it or rely on it. And if you can't do that,
it's a waste of disk space.
>Maybe I need to try a different backup utility? Thanks.
I had bought the Official Red Hat 5.0 distro a while back. This includes a
licensed version of BRU2000-PE (Personal Edition, version 15.0) together with
their xbru GUI frontend. It seems to work very well. BRU stands for Backup and

Well, I was a skeptic once as well, but am presently running a 300A

Make sure and run something with the 2.2.5 or better kernel. Much better
performance from a server with the new kernel.
Next, add lotsa RAM. Linux is pretty good about using extra RAM to cache the stuff
on the Hard drive. Especially things like databases.
Check your hard drive settings with hdparm. Try and tweak them. These settings
can really make a big difference.
A pair of large IDE drives run in a single RAID-1 mirror are VERY fast for
reads. Note that you can run more than two drives in a Linux RAID-1, and each
one increases read speed, but slows write speed. Real world improvements with
IDE would be nominal at best.

If the xterms are each running a different app, then could benefit from having more
than just two processors, but the cost would be prohibitive. Linux's only real
weakness is that the kernel itself doesn't run as fast on multiple CPUs right now,
but since the vast majority of what a Linux box does is in userspace, it still can
utilize those extra CPUs well.
If you are running a database on the machine, like mySQL or PostgreSQL, the extra
CPU is a must for a heavily loaded machine.
What does TOP say about CPU usage and swap file usage? If you are not maxing the
CPU, but using swap file, you need more memory, if you are maxing out the CPU, and
still have 20 or more megs in buffers, time to look at a dual Celeron 466 machine.

For a while the Diamond Fireport was a great deal, with the SymBIOS 675 on it, but
they don't make it anymore, apparently they forgot about a little thing called
marketing. But, I've had good luck with other SymBIOS controllers as well. I'm
not familiar with the HP U/W, what chipset does it use?
If you REALLY want fast I/O, buy hardware RAID arrays. There are several that work
with Linux well, and now AMI has a 1.00 version of their MegaRAID controller driver
out. That is a monster card, that can handle up to 45 drives on one card, and
seems to get faster under RAID 5 as you add drives right up to about 8 or 10
drives. Very nice. $1800 worth of nice.

Sorry, but the post picked up a line wrap. The above should be a single
line, with whitespace between 'vfat' and the rest.

The portege 300ct works just fine with linux...I have one and love
it.
The bad news:
- It's got a winmodem in it. You will have to use a pcmcia modem.
- It has some weird problem where you must make sure to eject all
pcmcia cards before suspending it, or it will never come back from
suspend.
Other than those things it works great! The screen looks really nice
in 1024x600 X. ;)
You should be able to do a normal install from any of the major
distributions out of the box.
If you need a XF86Config let me know.
