Start with a virgin 2.2.2 tree in /usr/src/linux ie:
cd /usr/src
mv linuz linux-old
tar -xzvf linux-2.2.2.tar.gz
cp linux-old/.config linux/.config ( to preserve your old configuration)
bzip2 -d patch-2.2.2.ac7.bz2
cd /usr/src/linux
patch -p1 <../patch-2.2.2.ac7
make config ( and answer all the questions)
make dep && make clean && make zImage && make modules && make modules
install
If you have redhat,
cp /usr/src/linux/arch/i386/boot/zImage /boot/vmlinuz-2.2.2-ac7;
cd /boot
ln -sf vmlinuz-2.2.2-ac7 vmlinuz
lilo -v
if you have most other distros
make zlilo

I was comparing the new compaq and the new palm pilot:
Compaq aero 2100 palm V
Ram MB 8/16 (24 max) 2
resolution 320x240 color 160x160
Size 5.27x3.34x.78 in 4.5" x 3.1" x 0.4"
Cpu 70 Mhz mips 16 Mhz 68k
Audio record/playback none
expansion compact flash none
Battery life 10 hours max [1] 20-30 ish real [2]
Alarms led, chirp, vibrate beep
backlight 2 levels on/off
Misc. One handed scrolling (dial)
[1] from compaq specs
[2] from usenet posts
Pretty amazing difference, 4-12 times the ram, 3 times the pixels, color,
vibrate alarms, compact flash support etc.
Seems like it would be easier with 16-24 mb ram+compact flash that it would
be alot easier/direct then squeezing it into a 8 mb ram, no compact flash
pilot.
Anyone know of a project to get linux working on one of these things?
Is this a bad idea to lend support to microsoft spec'd hardware?
Thoughts?

If you exported it (required for remote systems to mount the partition)
then the mount point truly IS busy (by the NFS daemons and/or mountd) and
hence cannot be unmounted. Try unexporting it first.

Use LILO but don't let it mess your Master Boot Record (MBR) located on
NT alias C: alias IDE0 drive. Let LILO write info to the beginning of
Linux partition (/dev/sda1 I guess). The following document tells you how
to add Linux into NT bootloader menu. Just read 512 bytes long boot info
from the beginningof /dev/sda1, save it as C:\BOOTSECT.LNX and add the
entry into C:\BOOT.INI file.

But never forget, stock Linux has only a resolution of 10ms (or 1ms on
an Alpha).
Shorter delays cannot be done with usleep().
There are some realtime add-ons for linux, however.

what you're asking for is to poll the keyboard. this can be done
by turning off cannonical input processing, and setting vmin/vtime
to zero. note that getch is quite different from kbhit, and
means ~canon and vmin=1.

there are some fairly whacked out patches that tweak or replace
the scheduler. but the fact remains: it _already_ supports realtime
and timesharing VERY WELL. in particular, I run highly time-sensitive
realtime psychophysical stimuli on an unmondified Linux box: during
the critical period, no other processes run, but that lasts only briefly.
like most such applications, there's slack time in between that lets
the machine keep the non-RT processes alive.

a dual-platform strategy. I've asked for a voodoo-II board, and
MS VC++ 6.0 to be procured on my behalf, so I'll try out the mesa-

Similar things happened to me also. There are a few version of
modutils-2.1.121-*rpm. The size of the files are different and some
are without the insmod.static. I tried a few of them, and one time
with the one without insmod.static I was in big trouble. This is because
if the SCSI module needs a statically-linked insmod to insert itself into
the kernel before anything on the disk can be used. (With the SCSI as
part of the kernel should have no problem of this kind.)
So should try some of these moduitls*rpm to see which one fits best.

I am having a problem: I get a core dump if I link my app to ccmalloc (a
leak checker). ccmalloc has worked on my older Linux boxes, and it works
fine on Solaris, but on either of two Red Hat 5.2 boxes (stock) it fails
the same way. It almost smells like there is a glibc issue here, but I'm
not smart enough about that kind of thing to know - hence this post.
Here is the gdb stack trace:

Does this make sense at all? Why die in kill()??? I might add that if I
don't link ccmalloc to it, it runs fine. I just want to chase down any
memory leaks!
I have reported this to the author of ccmalloc (Armin Biere
<[EMAIL PROTECTED]>) and he said that he suspected glibc. I would tend to
agree since it does not happen on a stock SOlaris machine.
Help! I want to use Linux with ccmalloc and this is killing me!
Any ideas?

The newer IDE controllers with UDMA handle two-way simultaneous

a supported feature with Windows 98. There was an add-on piece for
Win95OSR2 and WinNT4 supports it for most controllers.
