With #2 your wireless network can talk to a wired one.

Yes, this is quite feasible. I have exactly that setup using Proxim
Symphony cards. I have an old 486/50 running Linux 2.2 that has a modem, a
wireless card, and a regular ethernet card. We have some desktop PC's on
the wired net and a laptop on the wireless one. I set up the wireless net
as 192.168.2.0/24 and the wired one as 192.168.1.0/24. I use diald and IP
masquerading to hook up to the Internet. The 486 routes between all the
networks and also handles our home email and local DNS. Everything works
great.
You could probably also do this with bridging instead of routing but I
haven't tried that.

Hi Guys,
Thanks for your input, what I am actually trying to do is ascertain the heating
effect of several machines in a computer room. The place I am installing them in
want to know the heat output so they can check if their aircon unit is up to the
job. So, what they asked me was if I could tell them the heat output figure, which
is where I came in.
So, if I take the current (actual) x line voltage , this will give me heat output
in Watts right?

OK, then there's something wrong with the drivers and/or modules in there.

Do you have a SCSI card in the system? I thought you said the devices
were all IDE.

So you have a CD-ROM and a CD-RW? This could be a problem; it seems as
though the ide-scsi emulation of SCSI CD-ROMs doesn't play nicely with the
IDE CD-ROM driver. Next time you boot the machine, at the lilo: prompt,
enter the following:
linux hdX=ide-scsi hdY=ide-scsi
where X is the location of your CD-RW and Y is the location of your
CD-ROM. That should prevent the IDE CD-ROM driver from grabbing any of
the CDs. One of your CD-ROM drives will be /dev/scd0 and the other will
be /dev/scd1.

it does create an effective 'uptime' load factor, which, in my

the k7 is by far the cheapest and best performing player out there.
but I still have issues with the quality of bios on some of the
boards, as well as the support of the onboard ide chipset.

This is a FAQ. It looks like you didn't read them. Go do that, now.
Deja keeps them around; do a power search in this group for the keyword
"FAQ" and you should find a wealth of information.
When you boot the machine, enter "linux mem=128M" at the LILO prompt. At
boot, Linux asks the BIOS how much memory is in the machine, and some
BIOSes can only return a maximum value of 64M... so you have to tell the
kernel how much memory there is manually. Read the docs about LILO to
find out how to automate the process upon boot.

At least your estimate will be erring on the safe side, re the
apparent power vs. real power discussion.
The interesting question is of course if your estimate gives rise
to the need for a new airconditioner. Then you might want a more
accurate estimate ... better bring out that power meter!

Subject: SCSI problem configuring 7 devices
Date: 29 Feb 2000 18:51:01 GMT
Our system has seven SCSI devices (six drives and one tape
drive) that are all *detected* upon boot-up, but the last
device is not being mapped to a dev (e.g., /dev/sdf).
These devices are split between two controllers, one
integrated, the other in a PCI slot.
The /dev/sd* entries present are sufficient to cover all of
these devices, but nonetheless, the controller and only six
devices are configured in total.
Is there a configuration option so as to permit more than six
devices on the chain and the controllers? Or is it a driver
problem?
The system specifics:
kernel 2.2.5, an integrated Symbios controller (ncr53c8xx) and
an adaptec 2940U2. There are five 4-gig drives (not presently
running raid) and one 52-gig drive, complemented by an HP
Dat drive mapped to /dev/st0.
