I have not been able to solve this problem myself, but I do have more
information. The dual capacity reporting is a sign of having an ATAPI2 Zip
drive. Note that the two capacities differ by 16K. But changing the "A:"
jumper doesn't seem to have an effect!!!!
We now have four different sorts of ATA(PI) Zip drives - what are Iomega
playing at!
Despite Jeffrey's success below I have not been able to get ATAPI2 versions
working under linux at all. I can instantly solve the problem by replacing the
drive with a non-ATAPI2 model such as P/N 03019D00
I presume that a new Linux driver will be able to cope with these new drives,
but I haven't found one yet.
All these drives have the same Model number, which makes it very difficult to
get what we want from our suppliers. Watch out as ATAPI2 Zip drives are now
being shipped as both OEM (P/N 04057D01) and retail (P/N 02965D04) parts.
I am now fed up with Iomega.

Hi,
I can't play CDs through my SoundBlaster PCI 64. I can run cdplayer and it
plays the tracks from the cd ok, but nothing comes through the speakers.
Here are the facts:
* Can play under Win95. Read: the little wire thing is connected inside.
* Can play samples using 'play'. Read: /dev/audio works.
* /dev/dsp works too.
* Using kernel 2.2.2 with about all the sound support in.
* RH 5.2
* I've tried playing the cd and playing with the mixer settings. No effect.
* /dev/audio0 does *not* seem to work. Is this normal?
* cat /dev/sndstat gives "sndstat: Operation not supported by device"
I've tried everything I can think of and read every HOWTO etc. It's driving me
nuts.
TIA,
Simon Edwards

There're quite a number of companies selling sub US$1500 with specs like
AMDK6-2/333Mhz, 4GigHD, 32Meg RAM & 12.1" TFT. I'm currently running
Linux on Mitac 5033 (Mitac is OEM manufacturer for number of companies
in US including AMS Tech - Roadster series).. and UMAX, Sager and few
others are offering almost the same specs with the same price. Check out
running Linux on notebook homepage, don't have the URL offhand but you
may get the website by using search engines. Most of internal modems for
notebook are WinModem, so beware.. you may need to get yourself a PCMCIA
modem and network card.

Yup! I find it interesting that the Department of Justice is after
Microsoft for their "Monopoly", but the rest of the Federal Government
(DoD & NASA in Particular) is busy *increasing* the monopoly by
*requiring* electronic communications use an MS Office document format
(Word, Excel, PowerPoint, etc), and of course MS Office only runs on
Windows...;-)

Subject: Re: hard disk partitioning problems
Date: Wed, 10 Mar 1999 12:58:40 -0700
No information to help, but I ran into a similar problem during the
install of 5.2...
I've got a multifat partition (using System Commander Deluxe) with WinNT
4.0, Win95, Win98, and DOS 6.22 on it. When I went to install RH52 on
the system, it took no less than 4 tries for Disk Druid to get the
partitioning right.
I also use a Quantum Fireball, but mine's the 3.2 GB version.
I allocated 128 MB of disk space to my /swap partition, and the rest to
my root partition. However, upon examiniation, Disk Druid had created
an extended partition and three Unix partitions - the root partition
only worked out to about 19 MB - clearly not enough for even a minimal
Linux installation.
I've no idea what changed, but now it's working fine - and I can still
use Win95/98/NT/DOS. I had a wierd problem a couple days later with TX
timeouts on my NIC, but that problem also cleared itself up.

Quote from an old Archive Python manual...
When you insert a blank cassette in the Python drive for the first time,
it will be automatically formatted. The Python drive first detectes that
the tape is blank (about 10-12 seconds). It then formats the tape when it
receives the first WRITE command that stores more than 126 kilobytes of
data (total) or when it receives an ERASE command. The formatting operation
takes about 30 seconds.
If the first WRITE command stores less than 126 kilobytes of data, the data
is placed in the buffer until the next WRITE command exceeds the 126-kilobyte
buffer capacity and forces the stored data to actually be written to tape.
At the time the data is actually written to the tape, the Python drive
formats the tape before completing the operation.
So in a nutshell, don't worry about it.

They don't make them. Although the K6 family is cabable of multi-processing,
they are not the same as intel chips and no MB's are made to support SMP with
AMD. The K7 should correct this, but it will be much later in the year (if at
all) before they are available.

This is all true, but if you're at all concerned about floating point
speed, etc, what are you doing running your big number crunching job on
the same machine as you're running your GUI & Netscape? anyway, having
one processor doing the O/S and the other doing apps is *still* better
than having just 1 processor doing *everything*. Also remember that
*alot* of the apps run these days depend upon INTEGER speed as much, if
not more so than FLOATING POINT speed... from the Benchmarks I've seen,
at a given CPU speed (Mhz) the Intel machines are better at integer ops
than the Alphas...
I not saying Ix86 machines are better or worse than the Alphas, they are
different and have a different target mix of applications they are good
at...
