You can do this in a single command with cdrecord. Find out the
appropriate speed, `lun,' and such, and type:
cdrecord -v speed=4 dev=0,5,0 -blank=all

Certainly. It's possible to run such a thing in 8Megs or even 4Meg,
though I'd suggest at least 16Megs of memory to keep it usable.

In many cases, X will be unusable, even in 64Megs, not because your
"486SX-25" is a "25" but because it's an "SX", lacking the math
coprocessor.
To give you a few data points, I've run X successfully on a 16Meg
486DX-33; Netscape 4 would have been out of the question because of
the memory limitations, but Netscape 3 worked fine, though it took
quite some time to get started. Also, with 64Megs of memory,
486DX-66s run Netscape 4.51 with fairly acceptable performance, unless
you stumble on a web page filled with Java applets and animated GIFs.
However, I've also run X on a 24Meg machine with a 66MHz IBM Blue
Lightning chip. Like your 486SX, it lacked a math coprocessor. In
general, X performance was fine. BUT, certain operations (obviously,
those that used a lot of floating point arithmetic) took an
inordinately long time. In particular, every time Netscape displayed
an image, there would be an unacceptably long pause before the image
came up. If I recall correctly, running Netscape on a fast machine
with the display directed back to the Blue Lightning machine gave the
same result, so the X server, not Netscape, was the real culprit.
Similarly, the X server arc drawing functions were as slow as
molasses.
The upshot is that your machine will make an excellent text-only
terminal. If you want X, you'll either need to get people excited
about writing a floating-point-free X server, or you'll need to
upgrade to a 486DX, a 487, or a 487SX (depending on which options your
motherboard supports).

Hi here,
Could someone tell me if there are good (I mean REALLY good) &
free sound softwares available for Linux somewhere in the Web
world ??
What are the best sites for this ? (in fact I'm a jazz piano
player, and I'd like to find a program that would help me to
write down on a musical score the different parts of the .wav
files I've recorded)
Thanks a lot !

Hello,
When ever I run Quake multiplayer under Linux, my ping seems to go up
and down from about 250 to 700 every other second, making the game very
choppy. When I run Quake multiplayer from Windows though, it stays at
about 250 and runs fine. I have a U.S. Robotics 33.6Kbps modem. I'm
running RedHat 5.1 with kernel 2.2.9. I've used `irqtune` to set my
serial port to priority 0, but that doesn't seem to help. If anyone has
any ideas on what's causing this and how I might fix it, it would be
greatly appreciated.
Thanks,

since there is _no_ typist rpm on rufus.w3.org I doubt it's part of every
distribution. Found it on the web, though, and tried to install the newer
2.2 version. Going to get 1.0 now since the newer one does not work, at
least for me.

If you patched your way from 2.2.5 to 2.2.9: Are there any *.rej files
under /usr/src/linux? SuSE sometimes changes kernel sources. Maybe you
have to download the whole tar-ball from ftp.kernel.org?

You don't need to have write permissions for the *file*, but for the
*directory*, because actually you are chnging the directory, not the
file.

I'm trying to disable the plug and play feature through my comp's BIOS
because I think it's screwing up my NIC card. I'm running RH 5.1 on a
Compaq Prolinea 590 computer. Does anyone know what the shortcut to BIOS
key might be while my comp is booting?
Thanks.

Did you 'make dep && make clean' before 'make bzImage'?
