Subject: Booting problem after install...
Date: 19 Jan 1999 23:46:54 GMT
Hi,
I am having a problem booting Linux. After installing Slackware 3.6
with Linux kernel 2.0.35, the computer halts during boot and gives
the message
Kernel Panic: VFS: Unable to mount the root fs on 03:03
There doesn't seem to be any problem with the hard disk. We've
had windows NT on there for two months without any problems.
Also I can boot from the rescue disk and mount the root filesystem
and run disk checking program e2chk (?).
The hard disk is a 10.2 Gigabyte Ultra ATA IDE Quantum Fireball
EX 10.2 AT. The specs on it are 19885 cylinders, 16 heads, and
63 sectors. Linux doesn't return the correct specs from
probing. I've been passing the specs into the kernel on the
boot command line using "hda=cyl,heads,secs". I've tried
a number of different parameters on that line.
The documentation says that Linux may requre the hard disk
specs to be entered on the command line for some SCSI disks.
Why is it not probing/returning the correct specs for my IDE
drive?
After reading the Large Disk HOWTO (I don't know if my
computer has BIOS INT13 or not), I've tried to partition
the disk with different parameters than those given by the
manufacurer and have had the mounting problem mentioned
in the first paragraph. I even tried the maximum numbers
that fdisk didn't compain about cyl=1024, heads=255, secs=63.
When I try to give linux the correct specs, the BEGIN and
START fields in the partition table don't agree. Is that
okay?
Any help would be appreciated.

If you like it like I do, S/W and H/W building combos then this would be a
cool project indeed. I think I will build one in my spare time just for
fun.
I have a spare 16x4 or 20x4 lines display as they are the cheapest thing
you will find with the most chars and line.
I also have a 8250 (old uart)
A Z80 is also doing nothing along side with a 8k rom and 8k ram.
So I have every thing I need except a temp sensor for the cpu + ADC for the
sensor.
So the next step will be to start wire wraping.
If you could send me as much stuff on this system monitor and things you
recken I should put on the display.
When it's all done be expecting some code and a schematic diagram.
What do you recken are things that should be displayed?
currently I recken
*cpu temp.
*cpu fan speed.
*used irq's, used I/O memmory ranges.
*cpu work load.
*available free memmory.
please add

Subject: Trying to set up a SoundBlaster Pro
Date: Wed, 20 Jan 1999 06:18:49 GMT
Hi, I have a SBPro (ISA 16 bit) that doesn't seem to want to work.
In my kernel Config, I set it up as it asks me to (via the settings for
IRQ, DMA & I/O in the manuel). The computer recognizes my sound card, at
least that is what I think 'cat /dev/sndstat' is telling me, the output
looks like this:
#cat /dev/sndstat
Sound Driver:3.5.4-960630 (Sat Jan 16 13:07:25 PST 1999 root,
Linux C512692-A 2.0.35 #25 Sat Jan 16 12:17:05 PST 1999 i686 unknown)
Kernel: Linux C512692-A 2.0.35 #26 Sat Jan 16 13:08:09 PST 1999 i686
Config options: 0
Installed drivers:
Type 1: OPL-2/OPL-3 FM
Type 2: Sound Blaster
Type 7: SB MPU-401
Card config:
Sound Blaster at 0x220 irq 7 drq 1,5
(SB MPU-401 at 0x330 irq 5 drq 0)
OPL-2/OPL-3 FM at 0x388 drq 0
Audio devices:
Synth devices:
0: Yamaha OPL-3
Midi devices:
Timers:
0: System clock
Mixers:
#
I also have /dev/audio and /dev/dsp, They have a major and minor device
numbers of 14, 4 and 14, 3 respectively.
What doesn't work is when I try something like 'cat boing.wav >
/dev/audio' I get an error along the lines of:
bash: /dev/audio: No such device or address
So, my question is, after all that technical info, what do I need to do to
get sound to play, and do I really have an MPU-401? (if not, how do I get
linux to not look for it?) One last note, if I use the default settings
for the MPU-401 support stuff included in the SB driver, it still shows up
as unconfigured (now, I haven't gone through every possible IRQ, DMA & I/O
setting). I'm using kernel 2.0.35 (yeah, yeah, I need to
get off my ass and get 2.2prewhatever).

Subject: 8.4 GB Disk config question
Date: Wed, 20 Jan 1999 04:20:51 GMT
I have one of the Western Digital 8.4 GB drives. The linux startup and
fdisk both report this as 1024 cylinders, 255 heads, 63 sectors. The bios
says 16383 cylinders, 16 heads, 63 sectors. Which should I use? This drive
will *never* see a Micro$quish OS, but it might at some time see Be, or
possibly DR-Dos. I did use the 16383/16/63 under fdisk when I first set it
up, but I'm wondering if I should go ahead and change it.
TIA

Gerard,
My father has one of these, and it came with a short (20 cm) cable that
plugs from the "Audio Out" on the FlyVideo into the "Audio In" on his
sound card. This is an external cable that adds to the rats nets on the
back of your PC.
Have you put this cable in?
p.s. My father is using it under Win98 though.

This is correct. A second processor can add about 96% more computing
power (up to 4 CPUs total supported 'out of the box', I think?). This
is more than what Windows is capable of doing, it gets gains of about
80% or so on a second processor (see the benchmarks at www.intel.com
for exact numbers on the Windows benchmarks, this is off the top of my
head).
A couple gotchas: Need to build SMP kernel if it isn't already (to be
expected, I suppose). Also, some third-party kernel drivers may suffer
and make the Linux kernel crash if they aren't "SMP safe", so be
careful. Other than that, the rest of the system (apps and such)
shouldn't even notice the difference (execpt they always seem to be
running on a seemingly less loaded machine).
I've been running SMP for months without a single crash or mishap. It's
quite impressive to see CPU usage get shared in complex programs (like X
running a few things). My general setup: dual Pentium 2's on a 400GX
mainboard, Linux 2.2.0pre7, bt848 video capture board, lm_sensors, 3Com
905 10-baseT, on-board Ultra-2 scsi Adaptec 7890, Soundblaster AWE 64,
3DLabs Permedia 2 AGP graphics, and some other stuff.
Good luck!
Phil

No go with the 320 and 520. (But my 320 would love to run Linux if someone would
put the time into porting it).
Maybe with the 250 and C10. These both have PowerPC processors; but the fact
that they are also MCA may present a problem. I find it hard to believe that
nobody has tweaked the code to get this combo to work. (I'd try if I had one!)
Let me know what you find out. I work with RS/6000 PowerPC/MCA equipment
everyday and would love to see Linux running on some of them.

OK the MPU401 UART is part of your sound card so you will have to change the
settings for your sound card then try again everything else looks correct :)
or change the IRQ your lp port is on in the bios
Check the /proc/interrupts for a spare irq and use it instead :)

I've built systems around both the PII and various K6s and havn't had any
reliability issues with either one. There are however a couple of "issues"
with the K6 that you might want to consider.
There don't seem to be many good motherboards that are of high quality and
support the 100Mhz bus speed of the newer K6s. I've used the A-Open AX59
and the Soyo 5EHM with good results. These boards are really just about
the same with the A-Open having better docs. and more convienent dip switch
location.
Many Socket 7 motherboards limit your cachable memory to 64MB or 128MB.
Some of the ones with 1MB of cache will allow 256MB of cacheable ram if you
turn off write back caching (and take the small performance hit).
None of the "Good" socket 7 motherboards that support 100Mhz bus have UDMA
support under Linux. The very latest kernels change this but it is still
worth mentioning.

The most complete hardware health monitoring package is Lm_sensors.
Check it out at:
http://www.netroedge.com/~lm78
I'm one of the developers, and we vow to write drivers for any hardware
health monitoring which is in use and which we can get the docs on.
Currently, we seem to have pretty much all currently manufactured
mainboards with hardware health monitoring hardware working. We've also
got some docs and working samples of some chips which have yet to appear
on mainboards. We use an organized source code tree which makes it very
easy to crank out new drivers for undiscovered chips as they get our
attention.
The flexibilty of the package allows users to set up automated health
monitoring which can produce graphs of voltages, fan speeds,
temperatures, etc. (to be included in a web page?). Or, a simple script
can send an email to you in the event of a slowing/stopped fan, dying
power supply, or overheating CPU. The most I've seen similar Windows
apps do is set off an 'buzzer' or beep, which won't help anybody if it is
somewhere where you can't hear it. Lm_sensors is great for unattented
Linux servers/routers/embedded-products (.. my reason for initially
becoming interested in the project. ;')
We've also been exploring some uses of making some surprisingly simple
and cheap data-acquisition and control systems for monitoring sensors
out-side of the computer case. Such uses might include home security
systems, automated CNC machining with feedback, hobbies, ???
The project is under a GNU-type license. Please send questions/comments
to lm78(at)stimpy.netroedge.com (replace (at) with @... spam filter, ya
know...;')

But when it tells me where the installation CD is located I select SCSI
as the option, but then it keeps "scanning scsi bus..." for the rest of the

I have an Adaptect 2940UW SCSI controller and 2 SCSI CD-Roms... could it be
