Hello,
i installed the 2.4.0-test2 kernel with framebuffer support. know i want
to change the graphic mode (on booting).
i read the lilo-howto and help -> they say to add vga=ask to the
lilo.conf should ask me on bootup which vga-mode to use - but it doesn't!
so is there anybody u know what i've forgot or where to get a vga-mode-
list to try a vga=xxx perhaps ?

OK, quick explanation:
The 'buffers' number is the amount of memory being used to hold I/O
buffers, usually for the disks. This is what under DOS and Windows is
called the disk cache. The 'cached' number is memory that was used to
hold program text and which has not been needed for anything else yet.
When you exit a program, the executable pages are put into the cache
instead of being freed. If you run the program again while it's pages
are still in cache, they can be recovered and used without having to
load anything from disk again. This speeds things up quite a lot. If
a program needs pages for data or code, then the kernel will flush pages
from the page cache and I/O buffers from the buffer cache until it
has enough, but only when it has to.
If you look at the output of the free command, under the Mem: line is
another one with used and free memory numbers adjusted to account for
buffer and page cache. Those numbers give you a more accurate idea of
how much memory is really used and how much can be made available for
use.
And it's not unusual to be into your swap file even with plenty of free
memory. If you've got server process init code and such that hasn't been
used in a long time, the kernel will swap that code out in preference to
flushing disk buffers or the page cache.

Is this a troll? To automatically mess with the partition map would
take a detailed understanding of disk geometry, which you obviously
do not possess. Unless, that is, every disk is _exactly_ the same.
If so, you could dd a good partition map and dd it back to every disk
using an init script on the bootdisk. Something tells me that's not
the case and that this is a _bad_ idea. Do it manually.

Why don't you POP them all, hand over to your local mail server for
delivery and then use your favourite mail client to delete the older
mails.

Write down the the services that you want the server to provide. Disable
*everything* else. Configure the services you do want to respond only to
*your* network/IP range.
Comment the services out of inetd.conf, remove all the links to stuff
you don't use in the init.d directory. Check the man page for tcpd.

Well, troll. You're just extremely ignorant. Why not go and find out a little
more about what you're talking about before you vomit your nonsense over
every newsgroup you are subscribed to.
Rest of junk snipped, newsgroups trimmed and followup to advocacy.

Yup. Have you got some process grabbing all your memory? hdparm -T tests
the OS buffer. Sounds like your's is being used elsewhere.

You can do the same thing with the DOS fdisk. DOS will probably
boot faster. Norton Ghost Pro is probably the best solution over-all.

precisely as designed, and as you want. free memory is WASTED memory,
and linux tries to keep almost all memory in use. in this case,
it's caching files that, say, netscape might have read. obviously,
if some other use arises, the kernel can easily scavenge this ram.

a modest amount of swap use is also a good thing. programs (say, X)
always have some VM that they use infrequently, or even only on init.
flushing those pages to swap mean that ram is used more efficiently.

Do you have Linux with Samba on the Toshiba? I don't really see
how this relates to Linux. If it is relevant to this newsgroup,
post what version of Samba you're running, the client packages,
if you're running some front-end like LinNeighborhood, etc.

Most disks have a 255 heads, 63 sectors translation. For making a
partition table and a formatted 2 GB FAT partition, the number of
cylinders does not matter.
Assuming the disks should not be tested for bad sectors, only the area
containing MBR, bootsector, 2 FAT copies, and root directory need to
be copied.
For a 2047 MB FAT16 partition that would be 1+62+1+256+256+32 = 608
sectors. The 62 sectors are slack. This would take less than a second,
compared to minutes using DOS format.

The Standard I/O functions are defined as part of the language.
That has been been true since the stdio functions were officially
incorporated into the language specification with the first
ANSI C Standard, a decade ago.

OK. So I now have Plugger 3.2 installed as the application to handle
all the audio types. I get sound for midi and mpeg formats. Still I
don't get any sound for wav files. I should add that my browser doesn't
complain, it simply doesn't generate any sound. Is it possible this is
a problem with my sound driver or audio chip? It is a bit confusing
because the desktop sounds for the Gnome desktop are wav files and they
play ok. I don't actually have a sound card, the sound is integrated
with my motherboard (Intel SE440BX for Pentium II processor)? Recall
that the sounds it does play are very quiet. I have to turn my speakers
up to full blast to hear them a normal level.
thanks, Jesse

Subject: old "Imakefile"

I have an old application that includes an "Imakefile" instead of the newer
"Makefile." GNU's "make" won't build it, and I was wondering how to build
it.
Thanks.
