You missed a few, John, such as Compaq's 64-Bit/66-MHz PCI-FC
HA (120186-B21). But, in general you're right: As I said,
"Most I/O widgets are 33 MHz, 32bit, widgets."
But the primary point of my note was to refute the earlier
statement (by Michael S.) that "The new problem will be the
132MB/s limit of the PCI bus." The next (PCI) buses are defined
and ready to go - just waiting for a few good widgets.
Cheers, Bob

You may be lucky and have an internal modem that isn't a
winmodem, or it may be a winmodem that somebody has written
a linux driver for. If not, your only answer is to buy an
external one. Most internal modems are driven by windows
software, so aren't compatible with Linux. External modems
are more expensive because they have the operating
instructions in ROM so don't need drivers.

It's a good thing we have you here, in this thread, to correct and comment
on all the posts; without you, we would know nothing about power supplies
and apparently nobody else does; except you, of course. Thanks so much for
your input, Bob.
BTW, for anyone else who's interested in actual test results:

I have a Diamond Supraexpress 56e voice modem and I think
there may be some issues. I was reading this before posting
my own problem, but thought the two may be related. My
Diamond modem is used in both Windoze and Linux and I have
the same intermittent error in both OSes. It will connect,
then, at some unknown point, sometimes immediately,
sometimes after 30 minutes or more, disconnects, in both
win98 and Linux. I'm logging the pppd details and when my
modem disconnects the only entry explaining it is Hangup
(sighup). Sometimes, after a random disconnection, the modem
will not initialize and it has to be manually turned off and
back on to use again. I'm using the 2.2.14 kernel using the
modem for POP and pppd.
I believe this is a modem problem and have a vague memory of
seeing a script on the Diamond site when I first bought the
modem. I can't find it now, but I remember that it was a
series of custom commands to the modem. Sorry I can't be of
help. I have to use windoze for downloading linux stuff
because of this.

As far as I know, no to both. You *can* set both to 0 wait time, but I
wouldn't recommend it.
BTW, how'd you get lilo to bring up ntldr? Is NT on a FAT partition?

Thanks to everyone for all the info!
Ok, another question while I move to the realm of budgets (hey, I'm a
starving student). While I can spend $90 on a PCP&C Silencer p/s, what about
getting either an Antec or Sparkle (aka Fortron Source) p/s for less than
half the price? Is that case, which one would be more appropriate, the
Sparkle or the Antec (I like the thought of having that temp-controlled
fan)? How does their sound compare to that of PCP&C? Also, I will be getting
a Fong Kai FK-603 case, which comes with its own 250-watt p/s (which, as you
can tell, I will replace). Would it be worth the replacement? I've read the
review on Anandtech, and he then states in conclusion that the Delta unit is
quietest. Sorry for all the questions, I just want to make an informed
purchase. I guess the bottom line is: Antec, Sparkle, Delta, PCP&C, or the
original Fong Kai p/s (so many choices!!)? Emphasis is on sound, but power
is also a very significant issue (as always). Any addresses to any of the
questions above would be greatly appreciated!

What kernel version do you have? I'm no expert, but I know
that there is no USB support in any kernel earlier than
2.2.14 and that is very sketchy support. I believe that the
2.4 kernel is now available. Your only hope of running any
usb devices is to download that, or 2.3.99, the last
development version. You may be able to get the 2.2.14
kernel to recognize your usb mouse and keyboard, if not,
it's either a question of getting the latest kernel or
getting a mouse and keyboard that isn't usb. That is, if you
aren't using something that only has usb ports.
Sorry I can't be of more help.

I have a Diamond Supraexpress 56e voice modem that I have
been trying to use with both windows and Linux. I can set it
up and make a connection with no problem, but after a period
it hangs up on me. Under windows I had no idea what was
happening but, thanks to the logging abilities of linux I
have a few non-pointers. These are that there are no errors
of the type caused by line noise, and my pppd logfile
records what appears to me to be a normal disconnection. I
am still very much a newbie, so maybe someone can tell me if
the entry "hangup (sighup) in the pppd logfile means
anything.
This is not a pure Linux problem, as the same thing happens
when I run the same modem under W98. Intermittent
disconnections after periods of time varying between a few
seconds and over 30 minutes. I have an idea that a command
string may have been posted on the Diamond site some time
ago to correct hangup problems, but I can't find it now.
Is there anyone who can help me? I am (fortunately) not
entirely reliant on this modem as I have a 3.6 internal
winmodem as well, but I have to boot into windows to use it
and downloading Linux software onto my Windows disk is not
what I really want, especially as the Diamond is a V.90
modem.

For me is working but after a random time 1 sec to 30 min the pppd receive a

Actually I'm not that keen on the temperature controlled fan. If the
machine makes noise, it's bothersome but somewhat constant, and you
get used to it. If it's quiet, that's better, and you get more
comfortable. If it's quiet part of the time and then suddenly starts
making noise when the temperature reaches a certain level, the change
in sound may break your concentration even more than a constant
intermediate noise level. Best approach with a temperature controlled
fan might be to get the biggest p/s available, like 400 watts, and
hope that the fan is almost never on because the p/s is not working
very hard.
I'm happy with my PCP&C p/s but agree it's probably not a good deal in
strictly financial terms. You might consider keeping the standard p/s
from your Fong Kai case but replacing its fan with a PCP&S fan for $15
or so. Chances are they are both 12V DC fans with similar
measurements and CFM.
The other thing is keep power consumption low, even at the expense of
performance. Use low-rpm disk drives and don't overclock your cpu,
unless you really can't live without the speed.
