It is supported by RPM, it's just that your version is too old.

Subject: get/set IRQ vector in kernel version 2.2.x
Date: Wed, 12 May 1999 16:56:39 +0200
I'm trying to port a DSP-board driver from kernel version
2.0 to version 2.2. When starting up the DSP a rather strange
(and stupid) procedure is used. Some information is passed from
the driver to the DSP by writing it to irq vector 0x88. The DSP
then reads the info. The vector is then restored.
In the old version this was done simply by writing the info
directly to adderes 0x220 (4 * 0x88) in memory. However, this
no longer works. The kernel does a register dump with a message
telling it can't derefenece memory at address 0x220.
I can't seem to find any suitable kernel function for this low
level stuff I need to do. Any ideas?

A winmodem is a device which uses a $200 CPU to substitute for a $4 UART
in generating the clocked bit values for the modem output. This allows
you to slow your system performance, and your modem performance, while
reducing the initial hardware cost a little and boosting the
manufacturer's profit at your expense.
You would want to use it because (a) someone gave it to you and you
can't afford a real modem, or (b) you are stupid and didn't read past
"specially for Windows" on the box.

Date: Wed, 12 May 1999 14:58:25 GMT
Anyone got a good pointer to >developing< pcmcia support for a card in
linux. I am using redhat 6.0 and fiddling with the 3CCFEM656 combo
card from 3Com. I believe it is a 32 bit card. The networking part
is the most vital. I only dial with the modem when I go to my parents
house. I have a cable modem at home and network at work.
This is a common card that you can order through dell with their
notebooks.
Cardbus 3.3v
10/100 and 56K Megahertz modem
3c574_cs, 3c589_cs both yield
"GetFirstTuple: no more items"
as the main error. I assume it is a problem with having the right
memory available and accessing the right registers in the card.
Anyone want to mentor me? =)
I think it can be done.

Alas, my system started life as a Slackware box many many moons
ago (a.out vintage), and gradually evolved into its current
distribution-independent form... 8*) I think the glibc, xf86, and
egcs packages are the only things I haven't built from src...
xf86 and egcs came from 'official' binary releases, and glibc came
from RedHat...

Two solutions :

2) use a mailing-list agent like LISTSERV Lite or SmartList.

You open the file for read and write, seek to the end, get the current
position (aka the length), seek to the beginning, and then write
(length) bytes of zeros to the file. If you want security against a pro
physically taking apart your disk and getting bits off under a
microscope, write 0xFF, then zero, then 0xE5 to each byte, three passes
with a sync (or fsync) at the end of each write.
Look for a program called 'purge' in the old comp.sources.unix archives.
I wrote it about 1991 and I believe I contributed it. I got the 0xE5
from a security dude at DOE when I had clearance, don't ask why that
value, other than many format programs use it for the initial low level
format.

Yes, it was done, it did work, it was faster. I forget who did it, one
of the past or present driver folks. Look in dejanews. As far as I can
tell the reasons are political rather than technical. There are cases
in which the bidirectional algorithm is slower than what we have, but
in practice it must be faster because a lot of commercial unices use it
(or claim to), and it's faster in simulation. It isn't used because it

The US welfare system is broken. The liberals won't accept any change
which leaves a single deserving person without benefits. The
conservatives won't accept any change which allows a single undeserving
person to get benefits.
Uh, you meant a demo of bidirectional seek rather than the consequences
of rejecting any less than perfect solution, didn't you?

At least my SuSE 6.0 contains a manual page for cli and sti in
section 9. IIRC the man pages of this sections are in a separate
package.
cli/sti are probably macros which resolve to cli/sti machine
instructions on ia32 (and AFAIK only as long as you don't use

glibc2.0.7 and glibc2.1 both create the same soname file -
libc.so.6
There are incompatibilities. The documentation in the
tarball is amply clear about how these incompatibilities
come about, and how to deal with them. People who upgrade
their C libraries without reading the documentation are
accidents waiting to happen. I see no evidence that there is an
issue with the upgrade compared, say, to the libc5 to libc6
upgrade. The documentation is clear, libraries need to be
rebuilt/upgraded, and all is well.

Subject: How to make linux boot/shutdown rapidly
Date: 12 May 1999 15:44:51 -0400
When I close the cover of my think pad, or hit the right key
combination, it immediately writes the RAM to disk, then shuts off.
On power-up it does the opposite--reads the disk file into RAM and
starts executing where it left off. This even works when running
Linux.
I was having a discussion with someone about whether this is a BIOS
routine, or something even lower level than that. I thought that
Linux never allows anything to use the BIOS routines, so I was arguing
for it not being BIOS. But then, what is it?
If Linux is to be used in a consumer appliance (like a car MP3 player)
it needs to be able to boot and shutdown almost immediately. What are
the schemes that people have looked at for this? For instance, does
anyone know how the MP3 car player described on empeg.com solves the
problem?
I was thinking that one could write a kernel module that would imitate
my ThinkPad. When loaded it would immediately write the contents of
memory to a disk file, then shutdown the CPU. At boot time, you'd
need a new boot loader that would load the file back into memory, then
return execution to the appropriate place. Thus, shutdown would only
take as long as it takes to write RAM to disk (and if you are clever
you would only have to write the buffers that aren't just images of
one on the disk). Start up would take as long as it takes to read
them off disk.
Is there a reason that this would be impossible to write? Is this
being worked on already? I've done numerous web searches but come up
empty.
Thanks,
--Michael
