Hello,
using an old 486 with Socket2 on my Hifi-Equipment for sampling and playing
MP3. An AMD 5x86 on 133Mhz will do the job as long no mouse in X will be used.
Is there another old processor that will give more Power for this job in socket
2? Do a Intel D2/66 have more FPU-Power for decode as the AMD?
Bye

Hi!
I'm interested if exists a driver for the above card (RAID SCSI card
AAA-131U2 produced by Adaptec) for (RedHat) Linux. If exists, is this
driver included in distribution kernel or I need to download its
sources?
Thanks,

Get a rescue disk (I tend to use the CD-Rom from SuSE, although I
believe Redhat has a bootable CDRom as well).
Take the disk accross, and attempt a boot on the new box with the CDRom
/ Rescue disk, mounting the "old" disk as the root partition.
recompile the kernel on the new machine.
install the kernel with lilo
Reboot without the rescue disk.
For no apparent reason, I would refrain from compiling the AMD kernel on
the other disk.

"Snappy" parallel port video frame grabber device.
Is there any form of software that allows this to be used other
than from Wind*ws? I mean the Wind*ws software is fine (at least
the 1.0 version that I have), no complaints about it at all,
except for having to reboot the machine just to get to it.
I don't have much hope since a web search got zero hits but it

I just installed Linux on a 360cse a few weeks ago. This one has 20mg ram
and a 1G HD. Look for the tpdualscan program. You will need to run
X -probeonly and then the tpdualscan program in /etc/rc.d/rc.local. This
one really threw me. I also had to modify the xf86config file. I took
everything from device on and replaced those sections on the xf86config file
that Xconfigurator created. The best I can get on this setup is 640x480
8bit. I REALLY wish I could get up to 16bit, but oh well.
I tried Redhat 6.0 on this laptop and ended up putting redhat 5.2 on it
instead. 6.0 just didn't seem stable to me, but 5.2 is working flawlessly.
Since I used a 3com ethernet adapter to install I can't comment on the Zip
drive. When you run the install remember to use "linux floppy=thinkpad" or
else your initial bootdisks will fail.

I have tried everything I can think of (which may not be much as I am a

I even did an exclude irq 3, now they share IRQ 9 .... oh bugger.......

Greets.. I am running a server with a moderate amount of users.. we have
installed disk quotas, but unfortunately we have put everything on 1
partition. That means that any user who is over his/her quota, once
expired, will not be able to receive any more e-mail, because the quota
affects the mailbox size as well.
Therefore, I would like to reduce this filesystem by about 1GB, and move
/var to a new filesystem, without quotas. Is this possible, and how? I've
fooled around in fdisk, but I'm afraid to do anything.. there's no
clear-cut path on this issue(as far as fdisk mans go).

A serial connector goes to the serial port, not the parallel port :).
They both can be DB-25 connectors, but the parallel port is a different
gender then the serial port. I think that on the parallel port, the
pins are on the cable end, not on the computer end.

I don't remember the Laserwriter exactly, but unless it has the ability
for a single DB-25 connector to act as a Parallel, RS-232, or RS-422 (a
few Lexmark printers actually pull this off, but it is unusual), then
you will never get it to work on LP1. You need to set it up on a
serial port, /dev/cua0, or /dev/ttyS0, or something like that ( I don't
have a linux box here at work, so I can't easily check).
I believe the Laserwriter NT is actually RS-422, not even RS-232,
although I think RS-422 will take RS-232 signals.
Try hooking it (with a serial cable) to a serial port, and start
working from there. You may have to mess with rates and parity for the
port... if you don't have any luck email me, I have gotten an old
serial HP Laserjet to work, and it was not too terrible, so I know it
should be done. I can go lookup what I had to fool with. Even 10
years after it was designed, that Laserwriter NT is a sweet little
printer.
Hope this helps, it was all from memory, so take it with a grain of
salt.

Subject: Trouble with serial port
Date: Tue, 15 Jun 1999 14:43:31 GMT
Hello,
I've successfully installed Redhat 6.0 on my computer, but I'm having a
bit of trouble with the modem on the serial port.
For some reason, both under Windows and Linux, the internal modem seems
to be on /dev/ttyS2 (COM3). So I tried setting up a PPP connection, and
it connects at 28,800 and works, except that the port seems to be going
at an incredibly slow speed. Ping times to my ISP are 100x slower that
usual. I've heard that this may happen if something else is using the
same IRQ as the modem. So I checked the ports using setserial and I got
that /dev/ttyS0 and /dev/ttyS2 are using IRQ 4, while /dev/ttyS1 and
/dev/ttyS3 are using IRQ 3. So I thought maybe mouse is interfering
with the modem, and I did:
setserial -b /dev/ttyS2 irq 3
And connected again and it was still doing the same thing. Any idea on
how I can go about fixing this? Why is modem reported to be on
/dev/ttyS2, when the standard for it is COM2?
Thanks for prompt replies,
-Andrey

this would perhaps be better phrased as
x86 processors *have* a complex instruction set. how much of it is
*used* by your C compiler is another story.
the original impetus driving RISC was the observation than a CISC has
a lot of special operations but that compilers were not taking
advantage of them very well. if you've every compiled a C program and
used the profiler to find inefficiences, it's the same kind of thing
only now between compiler and processor.
the most basic form of RISC is as follows:
you take an x86 and restrict yourself to that subset of op-codes
which is emitted by, say, gcc. optimize these op-codes and throw away
all the unused cruft. now your compiled C code should be faster
(since you have optimized what you actually use) and the processor
smaller (since you throw out unneeded stuff). the new partial x86 has
a Reduced Instruction Set CPU (RISC) since you have fewer valid
op-codes than before.
now, take this idea and design a CPU which would have op-codes useful
to a C compiler. this new CPU may have many more op-codes, but they
would be such that the C compiler could easily use them. usually this
means having lots of generic registers. stuff like delayed branching,
aggressive pipelining &c are not RISC per se (since there's no reason
a CISC chip couldn't have them), but are now made practical and
worthwhile by the more straightforward architechture which the
compiler wants.
the x86 instruction set is notoriously bad for having compilers
generate code for it. it has few registers, they are all special
purpose and there are many weird op-codes which the compiler never
bothers to generate.
put simply the alpha is just more C compiler friendly in its
instruction set. it doesn't mean that stuff compiles quickly, it
means that the resulting compiled code is very efficient.
in addition, the alpha uses 64 bit registers for a wider memory
access. this means you can fetch (roughly) twice as many instructions
and move twice as much data per memory access.

Subject: Re: need backup hardware recommendation
Date: Tue, 15 Jun 1999 14:54:42 GMT
As others will no doubtedly point out, a CDRW drive is perfect for this
sort of situation, and is what I use for nearly the exact same setup.
For about $200, you get a reasonable (not the best however) backup
solution, but you also get a tool that does all sorts of other uber-
cool things, and the cost of backup media can't be beat ($3 per 600 MB+
of reusable media, $1 per 600 MB+ of permanent media).
As another poster pointed out in a similiar thread... those Travan
tapes don't sound very good in my car CD-Player :)
Checkout www.freshmeat.net for my package (backburner). This will give
you the foundation for exactly what you want to do, and allows all
sorts of backups of all different formats using existing Unix tools
(primarily tar, dd, and gzip). You will need to set up your own
strategies for image versus incremental backups, and probably need to
cobble together a few simple scripts. The documentation for backburner
also shows some backup scenarios and how to perform them.
Tape drives are better for an industrial high volume application, as
flipping CD's could become a hassle if you are always backing up tons
of data. For a personal machine or a small network however, CDRW works
great, and you can't beat the flexibility.
I generally make a full image backup any time I do some non-trivial
system configuration work on any of my Linux or Win95 boxes. I then
just re-backup my data directories (/home under linux, /data under
win95) once a week or so, or whenever I have accumulated a lot of new
important data.

other answers did point out how to do it with LILO.
with loadlin it goes the same, just add "mem=128m" like
loadlin bzimage root=/dev/sda5 ro mem=128m.
the reason why? memory can only be probed in the very early stages
of the boostrapping process, and some motherboards crash when
probed incorrectly. so linux knows too late when he can safely probe
the memory.
as 2.2.* kernels correct the problem (as far I know), things may have
changed a bit.
(btw, if you wonder, you would have hit the same problem with another
dist')
