I think he knows that the resolution limitations are 640x480 on a PAL set
and 640x440 on NTSC. This is in the PSC1106 Mini-HOWTO. His question
seemed more about display quality (ie, fuzziness and flicker) ;).
The fuzziness really depends on the size and quality of your TV set. Older
colour sets give the worst results (anything more than 80x43 text
resolution is illegible). New colour sets are okay up to 80x50. Black &
White sets and RGB monitors provide legible results at 80x60 text res.
Flicker is acceptable and only noticable if you're looking especially for
it :). Results re flicker & fuzziness in X are the same as when using
SVGATextMode (ie, the app that lets you tweak that text mode).
I might add that bit about the flicker and fuzziness to the the
Mini-HOWTO as I don't think I mentioned it there.

Actually, they are consistent with my results... until I turned off the
graphic display on the windows machine. After that, the windows machine
started to blow the doors off of my linux box (see earlier post for the
config and stats). When I started the first block, I started both computers
within 5 minutes of each other. When the linux box reached 92 % it had a
20% lead on the windows machine. At that point I turned off the display.
The windows machine ended up finishing 10 minutes after the linux box
completed its block.
So, I heard some discussion over the fact that the hold up could be the
graphics engine in Windows.. I'm starting to think that is true...

Not sure what you mean by "cable system"? The network is @Home and the
cable modem itself is a 3Com USR CMX.

No. Specifically:
eth0: 3Com 3c905B Cyclone 100baseTx at 0xe400, 00:10:4b:9a:82:e5, IRQ 11
8K byte-wide RAM 5:3 Rx:Tx split, autoselect/Autonegotiate interface.
MII transceiver found at address 24, status 786d.
MII transceiver found at address 0, status 786d.
Enabling bus-master transmits and whole-frame receives.
eth1: 3Com 3c900 Boomerang 10Mbps Combo at 0xe800, 00:60:97:c8:01:c8, IRQ 10
8K word-wide RAM 3:5 Rx:Tx split, autoselect/10baseT interface.
Enabling bus-master transmits and whole-frame receives.
BTW, dumping the packets from eth1 shows a slew of arp calls, so the NIC is
obviously communicating with the cable modem.

Reason #1: Because eth0 is a 100Mbps device (like the rest of the devices on my LAN)
and eth1 is a 10Mbps device, which is fine for communicating with a cable
modem.
Reason #2: I previously *did* have this card (eth1) working under Linux. I
replaced it with the 3C905 when we went to an all-100Mbs LAN. Having 2
NICs in this box is a first for me, but they don't seem to be in conflict.
I know that the hardware works. The NICs, anyway. The cable modem is
still an open quesion since I haven't yet successfully established
communications with the @Home network through it.
Thanks for the response.

These are loadable modules. If you compile yourself a kernel, indicating
you want 8390 and ne2000 support as modules, they will be rebuilt.

Hi all,
I am using Redhat 5.2 with kernel 2.2.5, recently the system reboots
itself a few times without any reason.
At first I thought someone has hacked into my system, but I could not
trace any sign as I checked through from commands such as last and
lastcomm, the necessary log files such as /var/log/message and
/var/log/secure, and crontab.
I disabled other services but only ftp and telnet, and these two
services are controlled by TCP wrappers in hosts.deny and hosts.allow,
which means the box only accept from trusted hosts.
Could it be having some hardware failures like hard disk, IO controller
and etc?
Please advice.

Because this is one of the problems I have been having with this kernel,
that is not being able to get ppp support. I get an error message that
ppp could not be loaded in the kernel.

It's been a few days since I looked at the article, but I recall the Linux

According to M.V. Ramana <[EMAIL PROTECTED]>:

I'd actually recomend running dual Celerons. They are every bit as
fast as the PII and about half the price. In fact, my single-CPU
Celeron 333 is actually a bit faster than my dual-CPU PII-333 when
running on just one CPU.

I'd recomend benching the fastest Celeron you can find against the

Standard rules apply. Make sure they have an 800 number. Make sure
they take credit cards and don't bill until the otder is shipped.

You may want to enlist the help of someone who has done it before. It

In the config, you were given the option of putting ppp in the kernel
or as a module. If you did neither, then you will have to rebuild it.
In the network option, check ppp y or m.
Then you should be able to choose the port, ttyS0, ttyS1 for com ports
1 and 2. Modem tool I think, only creates a link between /dev/modem and
/dev/cuax.

Subject: Hi, am having trouble with cpio-2.4.2 on S.u.S.E. 6.0
Date: Sat, 22 May 1999 16:46:13 +0200
Hi,
this program, cpio-2.4.2, as delivered by S.u.S.E. or
even as compiled by myself on the S.u.S.E. 6.0 platform, is
exhibiting buggy behaviour. The exact same source compiled by
myself on other operating systems is not. The problem is with
the -c flag. With libc.so.5 there is no such problem.
What happens is that header fields get placed "in the wrong
slots", as it where. And two of them are simply cleared
altogether, it's like two shift-registers, one with 6 byte
words and one with 11 byte words. Everything gets shifted down
one "notch" in both these imagined registers, and zeroes are
shifted in at the top. See cpio.h:
/* All the fields in the header are ISO 646 (approximately ASCII) strings
of octal numbers, left padded, not NUL terminated.
Field Name Length in Bytes Notes
c_magic 6 must be "070707"
c_dev 6
c_ino 6
c_mode 6 see below for value
c_uid 6
c_gid 6
c_nlink 6
c_rdev 6 only valid for chr and blk special files
c_mtime 11
c_namesize 6 count includes terminating NUL in pathname
c_filesize 11 must be 0 for FIFOs and directories */
All the 6-byte fields from c_ino and down form one thought
shift-register, and the 11 byte fields for another. All the
valies in these fields get shifted down one step using libc 6
compared to a cpio compiled with libc 5, or even solaris libc 1,
libnsl 1, libsocket 1, libdl 1, libmp 2. When using the -c flag
that is.
Other than running under libc 5, do you have a work-around?
Mabye a patch to libc 6 or possibly, if this is the culprit,
to libnsl (that is also used by S.u.S.E. 6.0 cpio)?
I have asked before about this, and at that time simply got the
responses that "it is known", and "it is only a problem with the
-c flag". While I didn't know #1, I was fully aware of #2, and
I still need this to work on all Unix-platforms I "touch". So I
need the fix.
It must be in copyout.c that things go wrong, but why only with
libc.so.6, etc:
ldd `which cpio`
libnsl.so.1 => /lib/libnsl.so.1 (0x4000b000)
libc.so.6 => /lib/libc.so.6 (0x40012000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x00000000)
?!
cpio-2.4.2 on e.g. Solaris does not have this problem.
cpiohdr.h defines struct old_cpio_header, and copyout.c uses
this structure when writing out the 76 byte header cpio.h
talks about, see it's format above. struct old_cpio_header:
struct old_cpio_header
{
unsigned short c_magic;
short c_dev;
unsigned short c_ino;
unsigned short c_mode;
unsigned short c_uid;
unsigned short c_gid;
unsigned short c_nlink;
short c_rdev;
unsigned short c_mtimes[2];
unsigned short c_namesize;
unsigned short c_filesizes[2];
unsigned long c_mtime; /* Long-aligned copy of `c_mtimes'. */
unsigned long c_filesize; /* Long-aligned copy of `c_filesizes'. */
char *c_name;
};
So, what goes wrong? I'll take a peek myself, also.
Thanks!
