Upgrade the kernel to 2.0.36 or higher, during the config script turn
on IDE FLOPPY support. I was having the same problem as you were until I
upgraded. Once the kernel supports it, the drive is /dev/hd(x)4 mounted on
/mnt/zip (which you will have to create). I believe the x is dependent on
the ide channel it's on. For example, my zip drive is hdd4 because it is
set to secondary slave. Good luck and email me if you need any help.

Much like telling her that she should press some keys to
logoff or shut the machine down or that she is going to
have to remember for herself under what contexts an item

That might be why some people have created ease of use
applets for such things and why apps that need to can
change the resolution on thier own.

Is the floppy connected to a floppy controller on the motherboard? If
so, what is the brand of your motherboard? Is the floppy connected to an
IDE-channel like an LS-120? If so you will have to compile a kernel or a
module with support for IDE/ATAPI-floppys.

Hefin,
Our current system is dual P2/350MHz on a SuperMicro P6DBS board, runs
great. We are using the intel pro/100, it also is great. We run a
distributed Oracle database and not a lick of problems. Averaging over
10GB/wk between the servers without a problem.
The local
university has 6 linux servers, including a full feed news server, all
using the intel card on dual
pentium/233s and have not had one problem. Very stable.
Good luck,
Daniel

Subject: can't get dial tone on modem
Date: 19 Mar 1999 13:55:29 GMT
I'm having difficulty configuring my modem. I'm running Red Hat Linux
5.2. I have a U.S. Robotics 56K Voice Internal PnP modem. It is
located on COM2 with I/O Range: 02F8-02FF and Interrupt: 03. This is
not a winmodem
What ever I do, I can't seem to get dial tone (I'm assuming I should get
dial tone since the speaker on the modem is not connected to my sound
card, which I haven't configured yet).
I boot linux using a floppy disk and everything else is on my second
hard drive.
When I login as root, I make sure to see that the software is configured:
[root@localhost /root]# grep -i "TCP/IP" /var/log/messages
Mar 14 13:41:25 localhost kernel: Swansea University Computer Society
TCP/IP for NET3.034
I then load the ppp stuff:
[root@localhost /root]# insmod slhc
[root@localhost /root]# insmod ppp
[root@localhost /root]# grep -i "PPP" /var/log/messages
Mar 14 13:52:55 localhost kernel: PPP: version 2.2.0 (dynamic channel
allocation)
Mar 14 13:52:55 localhost kernel: PPP Dynamic channel allocation code
copyright 1995 Caldera, Inc.
Mar 14 13:52:55 localhost kernel: PPP line discipline registered.
I then run minicom with the serial device set as: /dev/ttyS1 I then try
to initialize the modem in minicom but I can't seem to get dial tone.
What am I missing?
thanks,
Mike

I didn't say otherwise. I specifically stayed out of the CPU type/number
debate. All I said was that there are contexts in which turnaround is
not correlated to throughput and in those contexts all the user cares
about is turnaround. I was, in fact, merely countering the suggestion
that anything that improves throughput is automatically a good thing.

Date: 19 Mar 1999 13:55:33 GMT
Thanks to both Kyle and Lance.
I got the zip drive working finally, using kernel 2.2.3.
I was using the 250MB disk supplied by iomega. It was partitioned and
preformatted. So it was not a problem with the disk as Lance suggested.
I also had the scsi device files setup in /dev (/dev/sda*, /dev/sdb* etc).
So it could only be the driver problem.
I got linux kernel 2.2.3 from www.linuxhq.com and compiled it. It has
a more recent version of imm driver (0.2x) as opposed to the 0.18
I was using with kernel 2.0.36. I got the 0.18 version from
http://www.torque.net/~campbell
But I don't think you should get imm v0.18. Kernel 2.2.3 has in-built
support for imm 0.2. I mean, you can select imm support while configuring
the kernel.
It took me 3-4 kernel compiles to get everything right. For my micron
millennia pc with pentium II 450, I had to select the following:
general setup -> parallel port support (parport.o),
pc style hardware support (parport_pc.o)
scsi -> scsi support, scsi disk support
Elsewhere, it had an option for ppa or imm drivers. I selected imm.
The kernel probes the parallel port while booting. To do this and detect
the port type correctly, it needs parport.o and parport_pc.o precompiled
into the kernel. They should not be modules.
Then imm driver (also compiled into the kernel) detected the drive correctly.
The disk was assigned to sda and the partition check identified sda4
as expected for windows formatted zip disk.
Another tip, kernel 2.2.3 was too big to be make a zImage file even though
I selected minimal support. You can save a few minutes if you do
make bzImage instead of make zImage.

Hi,
I have two basic questions:
Kernel: 2.0.36-3
1) I have an Alps MD-4000 printer/scanner. I know the scanner isn't
supported and I know Alps doesn't officially support Linux (they'll come
around sooner or later). I was told that others have gotten their Alps
printers to work under Linux using the postscript driver. I tried it
but just got postscript garbage on print out. If this has successfully
done, could you let me know the trick?
2) I have a SoundBlaster PNP Awe32 sound card. I got it installed, ran
sndconfig and I can play cd's and .wav/.au files. On boot up I see the
error:
Soundblaster audio driver ...
SB 4.13 detected OK (220)
AWE32-0.4.2c (RAM8192k)
sh /sbin/sfxload: no such file or directory
failed ... /lib/modules/2.0.36/misc/awe_wave.o
sound: device or resource busy
and when I try to play midi (I installed the kernel patch) I can see
it's playing a file but I don't hear anything.
Anyone got any thoughts?
TIA,
Nicci

I went through all what I could think of (including HOWTOs), this is giving

Where should I look?
What services MUST be started at boot (maybe I forgot something)?
Is there some sort of "binding" I should take care of?
Else?
This is maybe obvious for you pros, but remember: NEWBIE is my name ;(
Any hints would be appreciated!!!

Since a regular 10-BASE-T/2 LAN is 10 megaBITS/second, by your implication
above, a 486 would have never "worked" in a LAN environment in the first
place... ("T1" is only 1.5 megabits/second, or about 8 times SLOWER than a
LAN in the first place)

True, this would be better -- you could probably then "do stuff" on this
system, but the idea here is to have a closet device -- something you can
tuck away and never [or very rarely] have to "get to it". Consider a
commercial dedicated router/firewall/print-server/etc and you'll see this
is basically the same thing -- a small box with only the needed ports (LAN
connections and maybe a serial port) along with an embedded version of some
unix-variant so you can "telnet" into the device and configure it. While
these "dedicated" devices aren't dirt cheap, they certainly don't cost as
much as a top-of-the-line pentium system [well, OK, you COULD pay that much
for a name brand one, but...]
Another idea, and I know one of the guys in our group is considering this,
is the "hand-me-down" super-computer -- a Beowulf cluster needs 17
computers [1 controller and 16 'nodes'], so by buying these "cheap"
machines he might just pull it off -- the raw math on this is that each
"node" will probably run $200 [$50 for the box/cpu; $100 for a 3gig+ drive;
$20 for a good NIC, and $30 for 32meg of ram]; 17 "nodes" then is $3400. I
don't know exactly how the CPU speed "scales" in a cluster, but I'll
"round" this to cover the areas I don't know and I come to 900mhz for the
"raw" power -- 60 (of 66) mhz * 15 machines = 900mhz. This is, admittedly,
a "close call" -- a dual-450 P-II with 256meg of ram and 18gig of usable HD
space probably runs around $3500 anyway. (and certainly doesn't take as
much desk space...)

No, you will have better luck if you lie to people about
how easy to use your product and force feed to everyone
through exclusive agency contracts.

However, you still need to know how to tell it to do
what you need done. The GUI only slightly improves on
that problem by limiting what you can tell the machine
to do.
Labor saving device != no learning required to use.
