Date: Sun, 14 Mar 1999 17:56:49 GMT
I'm getting some strange errors when I try to mount the AOpen CD-936E/AKW
cdrom. Im doing a mount -t iso9660 -r /dev/hdc /cdrom Also tried it without
the -r , and tried it with /dev/cdrom instead of /dev/hdc even though my cd
is setup as a secondary master. Here's a peek at the error message
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54
Zend_request: I/O error, dev 16:00 (hdc), sector 64
ATAPI device hdc
Error: Illegal request -- (Sense key=0x05)
Illegal mode for this track or incompatible medium -- (asc=0x64,
ascq=0x00)
isofs_read_super: bread failed, dev=16:00, iso_blknum=16, block=32
mount: wrong fs type, bad option, bad superblock on /dev/hdc or too many
mounted file systems
I also tried this in UDMA mode, and NON UDMA
I also tried different cd's in the drive, in case of a scratch on a cd
or something silly like that.
any help would be great!
thanx alot for your time
Justin

One of the greatest tricks Big Bill ever pulled was convincing people
that they should shell out money for more memory, then smile when they
checked & saw it was not being used.
Linux - any unix, for that matter - will use as much memory as you have.
It will be used for programs, of course - and memory beyond that will be
used for buffers, cache, etc. When a program asks for memory, Linux will
give up some of it's buffer memory for that program.
If you absolutly max out your memory resources Linux will then begin
swapping out to disk - you'll *know* when this is happening, and with
your setup - if it's just a single-user system - it will probably never
happen.
In short:
a: Don't use a microsoft measuring stick to size up linux.
b: don't worry about it - everything is running just fine.

On my system:
% free
total used free shared buffers cached
Mem: 47364 46340 1024 27720 3288 21644
-/+ buffers/cache: 21408 25956
Swap: 126892 1084 125808
21408 kB are being used for programs. (21644 kB + 3288 kB) = 24932 kB
are used for various caches, which will be thrown away if any programs
need the memory. 1024 kB is truly unused. The memory system likes to
employ memory for caches rather than leave it free; this helps to
improve performance (it is faster to read out of cache than off the
disk).

Subject: Hdd format problem
Date: Sun, 14 Mar 1999 18:05:28 GMT
Hi: I want to install linux instead of win95. My hard disk may be destroied
by some kind of virus (in win95), so I want to rebuild it under linux, I
have Redhat 5.2; Slackware3.6; debin2.0, all CDs are bootable.I want to
completely format my hdd using linux, I do not want to low level format it
but hope the hdd as clean as low level formatted. Is there any process in
linux to do this (make the hdd like a new one, just as we do in dos : fdisk
/mbr; format c: and even debug,,,,,)
Thanks in advance

Maybe. glibc (== libc6) is completely separate; it even has its
own dynamic linker (/lib/ld-linux.so.2).

% strings - /path/to/executable | grep libc
% strings - /path/to/executable | grep ld-linux
Getting something like "libc.so.6" or "/lib/ld-linux.so.2" is a
sign of glibc-ness.

In `/usr/src/linux/Documentation/sound/README.OSS', there is some information
on Aztech Sound Galaxy cards. I'm not sure if your card is the same, but
it's probably worth trying it out with the suggested sound modules to see
if it works. You may have to figure out how to use the `isapnp' utility,
as well, to configure the card correctly before using it. So, the best
advice is to try it and see. You probably have to go through this for any
soundcard you buy, so you might as well do it for the one you have (unless
you buy sound drivers from 4Front Tech. at `http://www.4Front-tech.com/oss.html',
they seem to make it pretty easy to get soundcards going).
