As a small follow up, I also ran hdparm against the raw devices. Here's
what I got.
[root@boots /root]# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 32 MB in 2.69 seconds =11.90 MB/sec
[root@boots /root]# hdparm -t /dev/sdb
/dev/sdb:
Timing buffered disk reads: 32 MB in 2.69 seconds =11.90 MB/sec
[root@boots /root]# mdadd /dev/md0 /dev/sda /dev/sdb
[root@boots /root]# mdrun -p0 /dev/md0
[root@boots /root]# hdparm -t /dev/md0
/dev/md0:
Timing buffered disk reads: 32 MB in 2.32 seconds =13.79 MB/sec
I'm, of course, no happier with this than I was before... Nor am I any
closer to understanding what's going on...

I've never heard of an "analog" computer, are there any advantages to it.
Does it process instructions at all... Is there a site I can go to?

I can't find any as well. The closest I could find is the BTTV
driver that work with Xawtv which include some capture applications.
Other than that, I couldn't find other device supported.

Date: Wed, 31 Mar 1999 00:42:16 GMT
Hi All,
Ok, I've been thru most of the digest and news groups but none of the solns
are helping me. I have a Dell Dimension XPS H233 running Redhat 5.1. I
installed that fine, however... when I try to upgrade my kernel to say 2.2.0
it can not find the root filesystem. I've tried almost all the suggestions
on the newsgroups.. building ide into kernel, scsi into kernel, making a
ramdisk with --needs-scsi-modules and with preloads ide-scsi aic7xxx but no
avail.
Anyone know the problem/soln to this?
Thanks!

No problem with BRU. Simply grab either the Jaz or Zip brutab from the URL
below and change the devname="my device" and size=nMB to match the L120.

Actually, I would just cook the triticale.
I sincerely hope it is overkill and a total waste of time. Either way,
though, it is extremely high quality organically grown food packed in handy
5lb sealed bags for long term storage at a reasonable price.
I figure it this way, if nothing happens I have a lot of good healthy food
around; if something does happen, I have a lot of good healthy food around.
Remember we are only talking about the price of an average serial card here.
Read the news story about Maine. This is not a test.

The Truth is all the processors are multiplier locked now. What that
means is the only control over the speed is the mainboard speed.
So a 366 Celeron is 5.5 x 66 Mhz
When the mainboard is changed to 100 Mhz you get the magic 550.
(5.5 x 100) . That preserves the PCI bus speed of 33Mhz (100/3)
Problem is, It will not boot....
When I set my Abit BX6 to 83Mhz It boots, but nic cards, sound, etc,
don't work. The very best resources on the net in MHO are at
www.tomshardware.com and www.sharkyextreme.com .
Beware though, I have 3 333 celeron and 2 366 celeron chips left
after my experiments, none overclocked more than meager amounts
even with quality memory and the Intel Boxed cpu..
goodluck

Huh? I have a 4GB drive on my 480CDT with:
1.8GB FAT32 Win95
1.0GB Linux System
65MB Linux Swap
1.0GB DOS Data
Or do you have an older BIOS that's picky about this stuff?
For something like that a 500MB root partition as the FIRST partition
works well. You can then create other partitions for /usr and /home. I
quite often leave swap for the last few scraps on a disk, but if the
machine does do a bit of swapping, using the second partition can reduce
delays due to the HD heads having to traverse big chunks of the disk. Go
figure, it made a difference on my 486...

You suspect correctly; see
http://www.picante.com/~gtaylor/pht/printer_list.cgi?make=Canon
The BJC-250 works with the bj200 driver for black-and-white, and with
the bjc610* uniprint parameter files for color.

My vote for an AGP card is the Matrox Millenium G200 AGP. It works perfectly
well on my RH 5.2 system. It's a decent card if you use the Windows OS, too.

what if you got files with names starting with a minus sign? minus

why not have a libc function do it? that way it'd be standard.
and what about regexps? those are done uniquely in every application
that uses them. i think a library should be made for those too.

that's retarded. you will quickly develop a reflex to hit `y' and
then you will be right back where you started.
what i want is a two-step process whereby i can mark files and then
once i am satisfied that i've marked the correct ones, i could delete
them in one shot. marking would be useful for all sorts of things,
e.g., moving files, submitting them to an application. i guess the
shell could keep track of the file marks.

emacs dired mode is more like what i'd like to see as far as deletion
goes.

Anyone know whether there is an updated driver for the 3COM 905B 10/100
Ethernet adapter? The issue that I'm trying to resolve is that the darned
thing doesn't work with 10mb/s DHCP. It works fine at 100mb/s DHCP, but not
10. This boggles me and I'm extremely close to just calling it quits with
3COM and going with an Intel 10/100. I like the performance of the 3COM in
Win9X though, and would also like to know if the Intel card is at the same
level of performance as the 3COM. Any and all help is much appreciated.
