Hello. Have you ever run this hardware successfully?
I have a FIC PAG2130 motherboard with a VIA Vt8501 Northbridge, which has
a VIA APollo MVP4 with on-board Trident Blade3D graphics and 82Cxxxx codec.
I have installed linux 2.3.99-pre9, back-installed the 1.1.8 82cxxxx sound
driver, and installed XFree86 3.3.6. Sound and video fail.
Actually, under linux 2.2.12 and XFree86 3.3.5, I got a generic server
running but I couldn't get 15-bit color (5 bits red, 5 bits green 5 bits blue),
which I need. Sound didn't work at all in worse ways than now.
Sound:When I use bplay to play a .wav file, bplay makes normal reports that it
is sending out buffers, but there is no sound (there had been sound with a
funny driver from FIC, but it cut off sound files and couldn't play all of them
but instead make a single click).
Video:
I ran XF86Setup graphically, but when it's done or when I later run startx,
the image of the screen is timed wrong and there are unreadable images of
a screen, although I can see movement of the pointer if I move the mouse.
So it's a little like being interlaced when I didn't want to, or putting
four rows of data on one line kind of thing.
If I specify the Chipset as blade3d, and run startx, it hangs the entire
system. I have tried setting options such as no_program_clocks,
no_pixmap_cache, "slow_dram" "pci_burst_off", but no difference results.
Have you ever seen this stuff work?
Thanks.

Hi there,
probably you have stair effect. I will not explain all details just try to
use next script -
name it unix2dos (Solaris command)
-- Start ------------------
#!/bin/perl -w
while(<>) { print $_,"\r"; }

chmod +x unix2dos
unix2dos [filename] | lp
now if it works just go into printtool and switch on stair effect option and
it should print correctly. I'd recommend to keep this script just for case -
it is not take much disk space.
NOTE: more details you will find in "Print How-To". I am wonder "Can you

Unless you crack open your CPU's packaging, you can't measure core
temperature. Knowing the core temperature is useless information unless
you have are designing the chip's packaging.
The rest of us can only measure case temperature (at the heat sink's
attachment point), which (not surprisingly) is the temperature that
manufacturer's publish in their data sheets.
As for some actual numbers (instead of blind assertions)....
According to Intel's P3 datasheets:
http://developer.intel.com/design/pentiumiii/datashts/24445207.pdf
http://developer.intel.com/design/pentiumiii/datashts/24526405.pdf
Maximum temperature of a P3 at the "junction" (hottest point of the
chip) is between 75 and 90 degrees C. Maximum temperature of the cache
chips (for those models that have separate cache chips) is 105 degrees.
Maximum temperature at the cover (where you and I can make measurements
without voiding the warrantee) is 75 degrees.
(Unfortunately, AMD's spec sheets only list case temperatures....)

I'm not surprised. It draws considerably less power. If the chip draws
1W of current, then it can generate at most 1W of heat.

The docs state maximum temperatures. They do not say that the core will
remain pegged at that temperature during normal operation. With proper
cooling, the core will not reach its maximum. That's what cooling is
for.

Which does not mean "pegged at its maximum".
If you only provide enough cooling to keep the temperature down to the
maximum, you are not providing enough.
As for Kryotech, their datasheet:
http://www.kryotech.com/Products/superg/Tech_Specs/sgsheet.pdf
says that they maintain a -40 temperature at the thermal plate. Sure,
the core will be hotter than that, but not 140 degrees hotter! A
temperature difference that great between the core and the packageing
would cause parts to crack and break off.

Most DDS drives will auto-set the density based on the media detection
holes in the cartridge.
If you insert a 125m tape, the drive will set itself to DDS3 density.
It will probably be impossible to set DDS3 density on a 60m, 90m or 120m
tape.

With all you hardware folks out there, I'm sure you've patches your kernel
once or twice. Well, to fix a problem with IP masquerading for FTP I need to
get my kernel up to 2.2.16. It's at 2.2.14 now.
I've downloaded both the .15 and .16 patch files, but am unsure how to apply
them. It's been at least four years since I did it last, and I can't remember

That would be in /usr/src/linux/README, which really has a nice set of

Date: Fri, 14 Jul 2000 16:15:31 -0600
Hello,
I'm trying to install RedHat 6.1 on my Dell XPS-T450 computer. This machine
has an older Adaptec AHA-2940 PCI SCSI host adapter in it. Everything works
fine until the aic7xxx module loads. At that point, the following messages
are displayed and the system hangs. Been through all of the various setting
in the CMOS and so forth but I don't see any problems. Here are the
details:
SCSI adapter BIOS version message at boot time:
Adaptec AHA-2940 BIOS v1.11S
Boot messages:
Everything looks normal up to here...

At this point, the system is hung. I've also seen the BRKADRINT error(0x8).
I think that is just the sequencer RAM parity error and no the PCI error.
This host adapter functions correctly under Windows 98SE so I don't think
that I believe that there is a hardware problem with the card or the basic
setup of the system.
Here's some vital statistics on the machine and OS:
RedHat 6.1 boxed CD (kernel 2.2.12-20)
Dell Dimension XPS-T450, BIOS version A04 (PhoenixBIOS 4.0 release 6.0).
Intel Pentium III 450 MHz.

Diamond Viper 770D 16MB.
12 GB IDE disk, 40 CD-ROM, HP CDWriter 8100.
D-Link DFE-530TX PCI Ethernet controller.
Yamaha DS-XG PCI sound card.
ISA serial port board - 2 16550A UARTs, no parallel port.
3Com/USR PCI winmodem (I'm not expecting to use this under Linux but I
do use it under Windows for now so I haven't pulled the card).
The additional serial ports are at 0x2F8/irq3 and 0x2E8/irq5.
I've been digging around on the net but I haven't been able to find anything
very helpful. Any help or advise would be greatly apperciated.

I'm about to spend some money to add wireless support to my setup (I want to
hook up one laptop to my other computers and the internet). How is the support
for the current 11 Mbs gold orinoco (wavelan) cards in 2.2.x and 2.4.x of
Linux, for both the pcmcia card and the card inside of the ISA adapter?
Have you used the residential gateway (RG-1000)? If so, what are your
experiences in connecting to an existing network? Is it even shipping?
I have multiple computers that are all in the basement, so if I go for the ISA
adapter, it would need to go through walls and such -- what is the realistic
range for such a situation? If the RG-1000 is workable, I do have cat5
ethernet outlets in the first and second stories of my house which would give
better range (and also I could shut down the gateway when not in use).
Do I need to worry about interference from other devices, including cell phones
and DISH TV remotes?

I've had no problems with the Vibra 16 card that I got last year. Here are the
conf.modules options I use for my setup:
alias sound-slot-0 sb
options sound dmabuf=1
alias midi opl3
options opl3 io=0x388

Just to be sure -- you did connect the CDROM sound cable to both the CDROM and
the soundcard? If you didn't, that would probably explain why you can play WAV
files but not CDs. This is a 4 pin cable you can get at most computer stores.

Yep. The CPU's core temperature will fluctuate wildly from second to
second as its load changes. The measurements we care about are the
ones from when the CPU is at a heavy enough load for a long enough
time that the casing starts to overheat, at which point the core will
cool much more slowly.

Hmm. If not for the fact that we're dealing with silicon, you could

Yes. You can try as many times as you like. I don't know that Linux
uses the boot signatures of boot sectors (AA55?), but if so, it might
go easier for you to search for that. It's the last two bytes of the
boot sector.
Be warned that Linux and Windows will both happily mount short
partitions that begin at the correct location, and will happily cause
catastrophic data loss when you write past the end of the partition.
(Actually, this may have been fixed in both OSes, but it was true the
last time I had the opportunity to find out.)
