Er, the only `style' Emacs enforces is that you have to know a bit of
Lisp to customize it. Its C autoindentation --- assuming that it what
you are driving at --- is *exceedingly* customizable. There's little it
cannot do, no matter how bizarre.
While, of course, it comes with styles that make it easy to conform to
GNU coding standards (and it *is* great for writing them in ;) ) it
comes with styles for other things, and it's fairly easy to extend in
simple ways. (Extending in complex ways becomes steadily harder, of
course, because you have to treat Lisp as more of a programming language
and less of a cookbook...)

Unix makes plenty of assumptions; so does Emacs; so does any
environment. As long as you agree with the assumptions, all will be
well. The problem with platforms like Windows, DOS &c isn't that they
demand you adapt to them but that the adaptations you have to do are so
bloody bizarre.

OH THANK YOU THANK YOU THANK Y...
I owe you a milion my friend. Just curious, where did you find
this information? Is it possible that I (little me) would find
such information on the internet? I have already read many web
pages and FAQ's about configuring graphics cards without finding
anything similar to "ChipID" let alone what chip ID the ATI Rage
has.
By the way, I don't have this distortion problem (which is the
original subject of this thread. I beg everyone of pardon for
getting off subject in my reply).
I can send my XF86Config file to those who have a distortion
problem in order to compare it with their own. Just email me.

Hmmm. Well, I've got a t-bird 700 MHz with a Gigabyte M/B with an AMD
751/756 chipset. Redhat 6.2 didn't like this - it installed OK but froze
on boot up with a kernel panic (something to do with disabling chip serial
IDs).
But..
This appears to be a problem with the kernel shipped with 6.2; I upgraded
the kernel and it now runs fine. So you may have to do this as well. (6.0
installs fine by the way).

Does this hold true for the Toshiba Portege 7100 series? I would think not,
but if anybody has any clues, I would appreciate it. RH 6.2 runs, but I get
no X, and no networking (almost got the networking licked). Looks like it
uses Cyberblade for the video, but still can't get X-Wndows to work

Also look in the manual that should've come with your distro; they
usually spend at least one chapter on configuring modems.

I just bought a D-Link DFE-650TX. I have a dual booted Toshiba Portege
7140, and the Windows side works fine. Networking is fine. On the RH
6.2 side, not so good. Can't get X-Windows configured. Every
combination of install I use says there is a problem, and can't figure
out how to get it to work. The Windows side says it is a Cyberblade
chipset, and I select that on the install, but no joy in mudville. Any
tips or tricks on getting X to work?
On the network side, everything loads up fine. It's able to recognize
the PCMCIA card, and if I do a ifconfig -a, it shows my lo and eth0.
But when I try to ping my default gateway, I get the following annoying
message:
eth0: trigger_send() called with the transmitter busy
Same thing happens if I try to modify my network settings using
netconfig. I can ping the IP address of my NIC card, and the lo
interface, but nothing else. I physically have link light status. Any
clues here? In linuxconf, I specified no kernel module (as suggested in
the How-to in linuxberg).
Thanks.

0. The output of "lsmod" should show the modules ide-scsi, scsi_mod,
sr_mod, and sg as loaded. If they're not there, modprobe them. It is a
good idea to put the line
alias scsi_hostadapter ide-scsi

1. The cdrecord binary must be SUID root for a normal user to make any
use of it. "chown root.root `which cdrecord` && chmod 4755 `which

It's usually better to avoid IDE CD-ROM support if you're working with
CD-R(W)s.

Subject: Diamond Supra external serial modem
Date: Mon, 31 Jul 2000 12:44:03 GMT
I have recently bought a Diamond Supra 56k external serial modem. I
believed that, because it is external, I should just be able to plug it
into my computer (running Debian 2.1), and it would work. That hasn't
been the case :-(
Wvdial does not detect it. If I send any commands to it - AT, ATZ,
ATDT, ATI -, using kppp or wvdial, the TR light on the modem comes on
for a few seconds , but the programs report no response.
I have swapped serial ports with my mouse, to make sure the port isn't
the problem, but the mouse continues to work while the modem does not.
I brought the modem into work to try it on a Windows machine and it
works fine here - I installed it as a standard modem to make sure the
signals are Linux compatible. I tried it again at home, in case Windows
had done any special configuration, but it still doesn't work.
Please help - I'm out of ideas.
Thanks

Hi,
My brand new PC has a soundblaster pci128 and it works great for sound
but, with redhat 6.2, I am not able to use the MIDI part of it. For
MIDI part I mean the internal midi player and the external connector
to control my keyboard (I have the midi cable and it works with windows
95).
My problem is that I want to use some programs as Jazz or Rosegarden
and they require playmidi to work. If I run playmidi I receive the
following error: "/dev/sequencer: no such device" and also if I
type "cat /dev/sndstat" I receive "/dev/sndstat: no such device" (the
file exists).2
How can I configure my Linux to see those devices ( need
also /dev/sequencer2 for the external port)?
Thank you in advance for the help.

Subject: [Help] Setting up 2.2.16: Problems with modules symbols and power down
Date: Sun, 30 Jul 2000 20:27:28 +0200
Hi all,
I've just grabbed the latest stable kernel version (i.e. 2.2.16). I've
configured (properly?), compiled, and installed it. It's running fine,
except for two annoying issues:
a) When booting up, depmod complains of undefined symbols in several
modules. I suppose it's due to a missing module-file, but how to
generate that file? I have set on the three options for "Loadable module
support", namely: "Enable loadable module support", "Set version
information in all symbols for modules", and "Kernel module loader".
Then make dep, make bzImage, make modules, make modules_install.
Finally, copy bzImage and System.map to /boot, adding entries to
lilo.conf, and executing lilo.
So can you tell me what am
I missing?
b) The second issue is a minor detail. When 'halt' is commanded,
everything is done all right except the last step, namely, actually
powering down the machine. I don't know why because the BIOS does
support the programmed power down and the previous kernel (2.2.14) did
power down the machine.
Thanks for your help.
Cheers!

Subject: network dies when I replace hub with switch
Date: Mon, 31 Jul 2000 13:21:49 GMT
I have a 2 PC network with one machine in the basement and one in a
bedroom upstairs. Both have 10/100 NICs in them and for the last few
years they've been connected via a 10Mb. cheapy noname hub which has
been working just fine. Both are running Linux 2.2.14. Out of curiosity,
I picked up a Linksys 10/100 switch just to see if 100Mb. would be
noticeable. Well, I thought I could just swap out the hub for the switch
and be done with it, but whenever I swap in the switch into the network,
I lose all connectivity! I can't ping either PC from the other or do any
other kind of network activity.
The cable run from PC1 to the switch is about 5 feet and from the switch
to PC2 is probably about 75-80 feet of cable. I am using CAT5 cable and
the box the cable came in says its 250 feet of cable. I've seen
documentation (with the switch) where it says fast Ethernet is limited
to 100 meters (368 feet) so I must be within bounds on that, since I
don't own that much cable! And there is still a lot of cable left in the
box.
It looks to me like the right lights on the switch box light up as
expected when I have the PCs booted up.
I also tried moving the two PCs physically right next to each other and
setting everything up. That did work. So my guess is that the problem is
related to the length of the switch -> PC2 run. But 75-80 feet should be
well within bounds. So why would I be having problems? And if I use the
10Mb. hub with the same cable, everything is OK. How can I more
thoroughly test my cable and fix whatever the problem may be? Do I need
to buy a signal booster and do they even sell such things for Ethernet?
Are they expensive?

Enable "Use real mode APM bios call to power off" in your kernel config,

You should run "make clean" before "make bzImage" :) Although this will
probably not remove the unresolved symbol messages.

Hi,
It could be that the cable run being used is not CAT5 compliant (could
well be CAT3 for 10baseT). CAT3 will work fine for 10baseT and could explain
why it
seems to work alright. If you can use drivers disks to force the cards to
10baseT
it may well be worth trying to see if that works for the 10/100 hub
The cables should have CAT5 or CAT3 printed on them - usually,
CAT5 is blue or grey and thick like power flex. CAT3 is a lot
thinner, like modem cables.
