But if it costs less, fills your needs *and* it works, what the heck.
You could buy six celereons for the price of a pair of Pentium II's.
Too much trouble for me, though, and I don't need to save the money
that bad.

Subject: adaptec 1520b/1522b scsi card not detected
Date: 26 Dec 1998 21:54:50 GMT
I'm installing redhat 5.1 and the installation does not find my
adaptec 1520b/1522b scsi card which is hooked to a cdrom
burner and 8 mm tape drive.
Looking at http://gatekeeper.dec.com/pub/linux/redhat/RedHat-FAQ
Line 16: Use this line for an Adaptec 1505, 1510, 1515, 1520,
and 1522 (and Sound Blaster SCSI). The reconnect and parity
are optional. For a CD-ROM hooked to ID 1 an a controller
with base address of 0x330 and IRQ 11 you would use:
linux aha152x=0x330,11,1,reconnect,parity
(you can try it without the last two)
I tried adding 0x340,11,2 for the options in the setup.
It then hangs looking at the scsi bus.
I'm going to install without scsi support and than try and
add that in later. Any suggestions?

I want to use my Linux system to handle voicemail, fax, and data. The
mgetty+Sendfax with Vgetty extensions FAQ section 'What does it look like

I'm a newbie myself, Redhat 5.1 - It works pretty well.
I struggled with my USR 56K Voice modem for days and days,
had several books open, and tried all manner of arcane
configurations.
What worked for me was the following line, entered pretty
much immediately after bootup:
setserial -b /dev/modem auto_irq skip_test autoconfig
This does depend on having the control panel pointing
at the right cua# (cua2 in my case, and I think yours).
If you set it that way in a previous X session that's fine.
There are a lot of options to setserial you could experiment,
but I don't know much about them. I have an ISA modem, Plug and Pray,
that is NOT a Winmodem. I made some progress employing /sbin/pnpdump
and /etc/isapnp.conf before someone suggested the line above,
on one of these newsgroups.
There is a slim chance that this will work for you. If not
I hope it helps give a clue to lead you to an answer.
I feel your pain.... :)

It may work but it may bomb randomly some day and destroy some hardware and
important data... I once had an overclocked machine in my company. The
person who sold us the machine was dishonest, we bought a P200 and got a
P166 overclocked to 200 w/o knowing that. Guess what, the machine went okay
for six months, then the problems begun: random crashes, corrupted files,
card failure, wouldn't work when it was too hot or too cold, etc. and that
cost us a lot of trouble and lost productivity for some months until I
called a hardware support person and he discovered the overclock. Even
after the fix, the machine is not something I would rely for any serious
job, and I would only sell it to people that I dislike a lot.

Just run the development kernel. From the comments that I've heard, the
newest development kernel (newest 2.1.132-- I could be wrong, they seem to
change hourly) is stable enough that it could be released today.

Subject: PNP Modem Problem
Date: Sun, 27 Dec 1998 00:56:26 +0200
Hello All,
I have a Boca 36.6 PnP modme.
I've configured a file using my pnpdump utility, and when I run
isapnp, it doesn't show any error messages, and detect the card.
So far so good, however, when I try to use my modem using minicom,
I do not get any response via /dev/modem, or /dev/cua0-3.
I tried configurating the modem, by running "setserial", with the
parameters I choose in my pnpdump, but still, I can't send anything
or recv' from my modem.
What to do ?
(Btw: how do I choose which comport will my pnp modem will take?
normal cards it's jumpers, and pnp cards, you can choose what you
want, as long as it's free, but how do you declare it in Linux ?)
Thanks!
Ozric.

Just watch out. H'ware DAT compression is rather stupid. I tested it
and found that if I back up already-compressed data then the compression
will actually enlarge the data. If you plan to use h'ware compression
then be sure to not use it on data that has a significant compressed
contents.
Also, in my experience with 'real' systems and using software (i.e. smart)
compression I do not get more that a 1.5 compression ratio overall. These
systems have both data, text and archived (compressed) data.
Finally the so-called 4GB tapes are actually under 3.8GB. The 2GB are
under 1.9GB. And if your backup uses a small blocksize then the capacity
is further reduced.
When properly used, DAT is very good bor backup, cheap too (especially
when you look at the total system cost including the media). Shame on
the stratospheric cost of repairing these units, often it is cheaper
to buy a new one.

Last I heard it the 2.1.xx kernels were up the M$ quality (about
125), and are not quite up to linux quality. If you need things that
are in the 2.1.xx kernels run them, or if it's your own workstation,
give them a try, but for a server, I would stick away from them.

In addition, most recent tape drives will do compression of the data prior to
it being written on the tape. That's how they get 8GB or more on a DAT tape!
Plus, the tape drive's compression is faster than Linux's, and the tape drive
can not compress what is already compressed.

You must not live in San Diego. Try buying ANY low cost new system here
with modem included which is not a PCI winmodem. Any the sales people
will always say "of course it's a real modem", because they don't have a
clue. And during the past 6 months modem manufactures (except for US
Robotics) seem to have decided that the "winmodem" label is unecessary,
as many brands of both "full" and "winmodems" now state that they
require MS Windows, without any discrimination.
While alternative workable ISA cards and external modems are available
for desktop machines, the situation with laptops is depressing. I've
been unable to find any with internal modems which are not (Lucent PCI)
winmodems.

And clone makers care about performance ? There is a performance penalty
for an ISA modem as well (limitation of com port on many machines to
115200, typically, which can be exceeded by a 56K connection with
compression), and the increased number of chips for a "full" modem is a
penalty for laptop power consumption. Lucent's chipset does the V.90
stuff in hardware, but V.34 in software, I believe, and I would bet the
performance hit for compression/decompression is typically not so great
as to be noticed by most users.
So I'm buying a laptop. I've got to buy Win98 anyway (unless I'm
willing to pay $1000's more or have someone else throw it away and not
tell me). But to run Linux and connect with my ISP, I've got to shell
out an extra $150 for a PCMCIA modem. That's really not a big incentive
for a would-be first time linux user, is it ? I think it is very
important to get one of the major manufacturers to release their specs
so that at least a minimal driver can be written.

See above. If, under Win95 a user can connect to his ISP without buying
additional hardware, but to use linux (the "free" OS) they have have to
shell out $150, I think agree with Norm Matloff that it's a big problem.

Winmodems are getting popular because they are *cheap* internal units
which use a DSP to perform the actual modem functions and the system
CPU to manage the protocols. Home PC's are a price-sensitive market,
and it is to this market that winmodems are addressed.
Just buy an external modem and you will be all right.
