Subject: HP Vectra IDE hard disk cable wierdness
Date: Thu, 18 Feb 1999 12:13:53 +0000
I've just taken delivery of a batch of HP Vectra PC's.
Looking inside, I noticed some wierdness with the IDE cables.
The CD-ROM is connected via a standard pitch 40-way ribbon, with
40-way IDC sockets on each end.
The hard disk is a Quantum Fireball 4Gb drive, connected to the
primary IDE on the motherboard.
The motherboard has the standard pitch 40-way plug, as does the
drive, as I'd expect, but the cable is high-density, 80-way,
with 40-way sockets on it.
Confused, I went into the lab, and grabbed the appropriate bits.
I tried very carefully sticking a 40-way IDC connector onto
some 80-way ribbon, and succeeded only in shorting all the
conductors together, so presumably these connectors are not
standard pitch, even though they have only 40 holes. (actually
39, one hole is masked out for keying purposes (why? not all
drives and motherboards are keyed this way).
What possible advantage to HP expect to gain from this? I'm
not about to take the cable apart to find out if two conductors
are connected to each pin. Is it a speed thing (I would think
it would slow things down), or a RF interference thing (without
the extra conductors being earthed, I'd guess not), so I'm
utterly baffled.

I guess you don't (didn't see the 166MMX thingie), but check the
help for this option that is provided with the 'make xconfig'
tool. My only 'experience' with SMP is when a friend tried to
get it to work on a PC from the university where he works. He
kept getting MTRR error messages.... no crashes though.

Try the ALSA drivers: http://alsa.jcu.cz, they fully support the whole GUS

Hi!
I've got a 4x Mitsumi CD-rom. Linux detects it as a ATAPI which should be
ok. But when I'm trying to mount it I'll recieve a message that fs type
iso9660 isn't supported by the kernel. When using a newer cd-rom I don't get
this message; the cd-rom mount without a problem.
Any solutions?!?
BTW - What do you think of running a 486 DX2-80 as a webserver/firewall?
Memoryrequrements? Others?
Thanks in advance!

The board is doing it just fine now, but in the PC of a
friend of mine :-)
I may ask him to remove it and put it onto the scanner, so
you can see the solder-points.
But it is not that complicate to find them on your own,
as long you own a multimeter:
AFAIR (half year ago), there are only two Voltage-Regulators (VR)
on the board. One produces 3.5V for V_IO and the other
produces 2.0-3.5V V_CORE (Bios-depended).
Both regulators have several leads (AFAIR):
Input: 5V,
Output: 2.0-3.5V or 3.5V respectivly
Virual GND
You should have a look at the Part-Number of the VR
(sorry, can't remember it) and get the Documentation
from the web (Ask Altavista). Then:
1. Find the GND-Pins of the VRs
2. Find the Regulator for V_Core
3. Follow the Output to a solenoid (or is it called coil?)
4. Solder the Resistor between GND of the VR and the "output"
of the coil

Can a PCI modem be used in linux? If so how? Something called a modem
enumerator is installed in windows along with the modem itself and i
dont know what that is. Its creative modmeblaster DI5630 v.90. Its
being used as PnP right now but there are jumpers on it I dont have the
manual so im trying to find out if com and irq can be hard set..

I've recently installed digi xe on SCO Openserver (eventually) There you
DEFINITELY need the digi mpi utility
SCO appears to have options to install it but nothing happens presume
linux is the same.
didnt look for linux stuff but im certain you need digi utilities -good

Is your SB-16one of the "vibra" ones? If so, try setting the 16bit DMA equal
to the 8bit DMA.

How much lines do you want to use ?
You can use the Eicon DIVA Server PRI/PCI Card for a S2M connection
with up to 30 channels. The eicon-driver supports this card.
The Eicon Quadro card with 4 S0 (8 channels) is not yet supported, but
I'm working on it.

Reply-To: "Adam Flinton" <[EMAIL PROTECTED]>
Dear All,
I am having the devil of a time with RH 5.2 due to it's going to sleep.......
I think it's down to the motherboard having an APM BIOS (Allows for power
saving etc) but I am now not so sure.......
I have swapped the MoBo but the second also has an APM BIOS. I have
recompiled the kernel a bunch of times with the different APM option & have
the watchdog function started. I also have the APM Daemon starting on boot
up.
I have a base Rh5.2 install with nothing else loaded (e.g. KDE / a DBMS etc)
Symptoms:
If I have the Monitor saving set to "always on" then I can see the screen
with the logon or whatever the screen is showing. The cursor is blinking etc.
However no response from the keyboard or the mouse to "wake it up".
The only way out at the moment is to switch the machine off.
The CPU is an Intel Pentium 133
The Motherboard is P5I430VX-250DM Explorer II
The BIOS is Award 4.51PG Energy Star V3.4S
The Drive is a (from /var/meassages) ST36531A, 6204 MB, w/ 128kb cache, CHS =
790/255/63, DMA
divided into 2 125 mb Swap partitions & the rest into 2 main partitions / &
/home.
Any thoughts welcome as it's really tedious as it used to run day in day out
when loaded with RH 5.1. I don't know what the difference is or what the
problem is as it exhibited the exact same symptoms on the last board which
also has APM once I shoved RH5.2 on it. Maybe it's not the APM though loading
up the APM daemon & compiling APM into the kernel has reduced the number of
lockups (though not stopped it entirely). Before doing this if I had the
board APM set to 1 minute for everything (for testing) then a couple of
minutes post boot it was locked. Now it will wake up most of the time but
everynow & again it locks (around once / twice per day). If I disable the APM
in BIOS it doesn't seem to make much difference if any...........
Basically if I'm using it, it's fine but if I leave it it goes to sleep. The
Cursor is there & flashing but not even the Num Lock / Caps Lock etc works.
Any thoughts helpfull
Adam

Subject: Re: C Programming for ISA Card
Date: Thu, 18 Feb 1999 13:16:51 GMT
I took a quick look at their web-site and couldn't tell exactly which board
you have. Nevertheless, their digital I/O boards look quite simple,
controllable with simple input and output instructions at the asm-level.
Thus the boards can be controlled easily with C using the input- and
output-functions that are in the implementation-specific portion of the
library that came with your C-compiler.
You have two choices:
1) a "super-user" program which allocates the I/O ports corresponding to
the board to itself and directly writes to the board
or 2) a device-driver which is loadable and does much the same, but is
usable by all users.
Option #1 is simpler if you (or the person using the computer to use the
boards) have a su-account or your sys-admin is willing to create a
suid-shell or program for you.
Option #2 may be simpler administratively, but writing a driver, while not
brain surgery or rocket science, is not as easy as writing "data =
inp(port);" If you do choose to do this yourself, there's a very good book
from O'Reilly on the subject
Norm
(Yes, I could do it, but I won't offer, even for money).
The choice is yours.

Well, in a Linux device driver, operations can be scheduled at the level of
the system clock frequency, usually in the range of 100 - 1000 Hz. Also,
for short delays (a few microseconds), software timing loops are normal.
And finally, if the printer is ECP, the DMA controller can deliver data
exactly when the printer says it wants another byte or three. I don't see
that as a major problem for Linux or any good "pre-emptive multi-tasking
system" for that matter.

Some motherboards, particularly if they're allowed to shadow ROM or the
adapter space 000A0000 thru 000FFFF, wind up with slightly less than the
amount of RAM you think you have installed mapped via special hardware
registers. I've seen some that were short by as much as 384K (hint 1MB -
640K). If that happens, LINUX might be using what it thinks is the top of
memory for a stack and if the memory isn't there, whoops...
