Sounds like a problem I had with one of my 300A's on my Asus P2BD when I
overclocked them to 450MHz.
It'd reboot without warning. Worked fine in Windows or at 375Mhz. After I
upped the core voltage from the default 2.0 volts to 2.2 volts on the problem
CPU. The crashes ceased and it hasn't spontaneously rebooted since problems
since (a month ago).

Hi,
I just installed Red Had Linux 5.2 and it runs fine, but I am having
trouble configuring the SVGA server for my video card. The card is the one
built into the motherboard that comes with the Media GX chip. I can "starx"
and see the screen, but everything is too big and spills over the edge of
the screen edges.
Has anyone successfully configured this.

Anyone looking for good used 20" monitors should start looking
for older SONY workstation multi-syncs. I don't know the SONY
model numbers but some HP model numbers are
A4033A (or C) I've seen these and their SONY equivalents for $300-400
A4331A (or C) I've seen these for $500
I worked for HP for 10 years and used a number of SONY workstation
monitors and all have been awesome for their day and, if still tuned,
still are. I'm currently using a A4576A and it is the most awesomest :-)
of them all. Of course, it probably cost $3K.
(Be careful of HP models ending in B or D - these are usually southern
hemisphere models which may have slight convergence or purity problems
up here. I never did find put what the difference between A and C or
B and D are)

It's a mixed blessing. Count the number of times there are questions
on this group from someone who has bought or downloaded Redhat, and
doesn't know how to partition a disk. Or even that they can't run
Linux under Windows! A recent question posted was "Where's the
setup.exe for Linux".
However if these people *can* learn, then they become an asset to
the Linux community, and to the non-Microsoft world.
Redhat does put *barriers* to understanding, by making things look
more GUI, and hiding the nuts and bolts. Again this is both good
and bad.

You dont say how you configured and partitioned the drive.
typically, NT is the only OS that i know of that lets you put it anywhere(Linux
if booting from floppy), +/- 1023rd cyl, hda-hdd, linux on the other hand, has
difficulty with anything other then under 1023rd cyl (514Meg?) on hda for
booting purposes. (That is root "/" has to be there) everything else, /home et

Subject: sleep_on / wake_up problem, full-duplex, SoundBlaster 16
Date: Thu, 1 Apr 1999 08:45:05 +0200
I would be happy to have a solution about a little sleep_on/wake_up problem
I have.
First,let me explain what lead to the problem:
I recently change a SoundBlaster PRO for a SoundBlaster 16 and i have decide
to build my own driver as a loadable module (Voxware sound driver work !).
In my driver ,I have implemented a full-duplex capability as it is possible
with a SB 16, by using of the two DMA channels (8bits and 16bits) at the
same
time. I use 16bits DMA for recording and 8 bits DMA for playing, both DMAs
share the same IRQ but a soundcard status port give the info on which
DMA (or sample size) it's occuring. Status gives 0x81 for 8bits, 0x82 for
16bits (and 0x83 for both but this should be avoid, maybe).
Basicaly, the driver work like this. At init, two DMA buffers are allocated,
one for each DMA channel, interrupt is registered without SA_INTERRUPT.
When writting, the write function try to fill as much as it can the DMA
buffer ,if the buffer is full the proccess go to sleep through a call
to 'interruptible_sleep_on' and is wake up by the interrupt routine when
there is available space.
When reading, the read function try to read as much as it can from the DMA
buffer ,if the buffer is empty the proccess go to sleep through a call
to 'interruptible_sleep_on' and is wake up by the interrupt routine when
there is data available.
To demonstrate myself the full-duplex, I have built a little program which
does this :
1) set read to 16bits 44100 Hz stereo
2) set write to 8bits 44100 Hz stereo
3) in a loop send data read from soundcard to the soundcard (after signed
word to unsigned char convertion)
This produce an echo effect, and it works.
Here is the problem, it happen that the program never wake up.
That arise when apparently interrupt for 8bits and 16bits are merge.
When buffers are synchronise, it has never happens.
By synchronise, I mean that the 8bits buffer length represent the same
sampling time as the 16bits buffer length, as long as the two DMA doesn't
start at the same time all work fine even with 8bits buffer length of 128
bytes, which is an interrupt rate generation of 689 Hz (8bits stereo 44100
Hz).
If both buffers represent different timings, after a while the program stop
'echoing' but don't hang the system.
The Question:
Does anybody knowns about how to fix me, or can give me a guideline to
follow
for a full-duplex operations ?
Note:
I used linux 2.0.0 (Slackware 3.1) on an IBM PS/VP 486DX2 66 Mhz with 20
Mb.
The driver is for my personnal use.
" As of version 2.0.0, linux still don't recognize my 2 harddisks (Maxtor)
without specifying the geometries, even with brand new E-ide driver.
OpenBSD does recognize them without help !
And I don't tell you about Mitsumi CD driver "mcdx" which, when doing
a simple 'find /cdrom -name *.lsm -print > lsm.all ' command, slowdown
the
system in a way that I must wait a bunch of seconds between each char I
type
or when I switch to another virtual console ..."

Hi Colin,
yes I've read what you are probably referring to:

According to
http://www5.pc.ibm.com/us/products.nsf/$wwwPartNumLookup/_33L4618
Supported software: Microsoft Windows 98, Microsoft Windows 95,
Microsoft Windows NT 4.0, Microsoft Windows 3.1x, IBM OS/2 Warp, SCO
Unixware, DOS 6.x and 7.x
This list is certainly missing something.
I am just eager to hear from the happy owners of ActionTech PCI modems
that they are indeed happy and run this modem under Linux.
Anybody?.. Have I missed their posts?
Cheese,
Andrew

You must change the permissions of /dev/dsp and /dev/audio. Try doing:
chmod 755 /dev/dsp
chmod 755 /dev/audio
as root and that should fix the problem.

First, Thanks for taking time to read me (my english is not so good)
In september last year I bought an Amd K6 3d 300 who never worked as
good as he does so after 5 month of 'reparation' from my Computer
Reseller (They are the badest I know) They gave me an Intel Celron 300A
with an Asus Motherboard.
And now I can't poweroff my computer with Linux (Under Window$ it work).
If anyone had an idea ??
It would be great.
