good move.   also, keep in mind that linux can mount windows partitions
just as easily as it can ext2 partitions.   you can boot linux, traverse
the windows filesystem and copy important files to linux space where
they'd be safe.

as far as kernel panics, the most common reasons are serious hardware
problems, forgetting to run lilo and a root filesystem in the wrong

btw, some versions of windows (like 2k) report foreign bootloaders like
lilo or grub as boot sector viruses.  don't take them seriously.

there are lots of different kinds of errors that can happen when an
operating system initializes.  some of them are harmless "you don't seem
to have a microbus channel!".   some are more serious but non-fatal
"module eepro.o failed to initialize".   some are fatal.  not being able
to find a root filesystem, for instance, is always fatal.

here's the good news:

unless you are a microsoft employee who does kernel development, a
kernel panic is REALLY hard to fix in windows.  however, under linux,
kernel panics are usually easy to fix.  it's much easier to fix a
motorcycle that has "no power" than it is to fix a motorcycle that has
flakey behavior or intermitant problems.

you're probably correct about this, although i wasn't aware that this is
a problem for windows 98.   AFAIK, 98 is happy to share the hard drive
with another OS.  this is the most common scenario for non-NT type OS's:

1. install windows
2. install linux

when you install windows, it'll probably want to take the whole hard
drive.  there are two options that people usually take:

1. partition the hard drive before installing windows.  use linux fdisk
or cfdisk for this purpose.  let windows take hda1.  when you install
linux, let it take the other partitions.

2. install windows.  use a program like fips to split off a big chunk
of your hard drive.  use linux fdisk or cfdisk to partition the big
chunk however you want.

it can be a tricky business.  however, it *should* be straight forward
with 95/98.

apparently, fdisk /mbr has some caveats that i never knew about.  you
may want to look at:
