a fast CPU can burn 50-70W all on its own.
also you need to accomodate peak power/energy requirements. e.g., a
disk spinning up draws much more power than one already spinning.

I think it may partition problem. Windows 98 support 1 primary partition
and other should under ext partition and logical partition.
I'm not sure that Windows 98 can works fine if linux partition (ext2) have
been add more than one and it's not under ext partition.

Hmm, the problem is I don't want it buy it unless it *defnitely* will
work :). It'll probably cost me about �75-90 GBP, so it's fairly
expensive if it won't work :(

I've been debating between the G450 and a Geforce2 MX. But the Geforce
will be >= 2x AGP as well, and I'd rather the Matrox overall. Just as
long as it gives OpenGL support under Windows, and is well supported by
Linux :)
Thanks for the PCI suggestion though -- something to bear in mind :)

Linux supports some hardware, compaq servers IIRC, which have pci
bridges. Also some alpha servers. So in theory, yes. However, since few
people have this hardware, you can't expect it to run flawlessly. Be
prepared to debug some failures yourself and connect with the kernel
mailing list.
Good luck

I went through the same thing a while back while migrating to a Mylex 170
card. Search for the "hard-disk upgrade howto", that will give you several
ways of moving the contents of the drive. If you're using qmail, be sure to
do "make setup check" from the source to ensure that it's special files are
set up right, and have qmail-queue on hand to fix the queue.
Once you get it moved over, update your /etc/fstab to look like it
*should* once you're running off of the new controller, then run
"mkbootdisk". Power down, remove the old controller/drive, boot to the
disk, and you'll be running from the new array. Edit the /etc/lilo.conf and
/etc/fstab to look like they should, run lilo, remove floppy, reboot.

Trouble is the currents you mention are running currents, not start up
current, which is always more. I had a PSU that if I was lucky would
start the computer 3 times out of 4. Just wasn't enough to cope with
all the drives spinning up at the same time. A larger PSU cured it.
I'd go along with the inadequate cooling theory. One HD yes but 2/3 it
would certainly have me looking at the case design. Are the hard disks
mounted one on top of one another? Any gaps between them etc for air
to move around.. How many fans?

I had a similar problem when I had 2 serial ports enabled to the same address.
They'd both XMT, but rcv was scrambled.
On the motherboard - is IrDA disabled? (that uses a serial/COM port).
If the modem shows all the handshaking lines then it would do the same
as the little 7 LED RS232 tester: see that the PC is asserting all the
status lines appropriate for a DTE.
D'oh! Is the modem set to assert DSR, CD and such?
Some drivers won't receive characters until the hardware handshaking is set!
(I kinda recall modems having switches to assert handshaking
even when on-hook/hung up).
(that's why I still prefer a DOS boot floppy with old old Procomm
to debug serial channels: it easily sets to any COM port
and can be set to receive with no handshaking)

I am not sure why you would want to do this on a Linux box, unless it
is strictly for effect. If you wanted maximum through-put and you have
access to dark fibre, it would be better to go with Gigabit ethernet
with transievers plugging into switches. If you are going through a
true Sonet network and therefore want packet over sonet, I would
strongly suggest using a dedicated router.

Realistically, we don't. I have some small computers here which have 600
MHz CPU's and higher, a CD-ROM, a hard drive, a floppy, and the built-in
LAN, sound, and video of the i810 chipset. They run quite happily on a
110-watt power supply.
Now, there is the fact that a motor draws MUCH more power when it starts
than at full speed, so if you have a large number of hard drives to spin up,
you'll need significantly more power - but then again, these little machines
can spin up two IDE drives without any problems. Unless you're running a
terribly fast CPU (especially the AMD's) and have plenty of hard drives, a
220- or 250-watt power supply is much more than enough.
In fact, if anyone doubts that statement, listen to this. One of the
machines I take care of is a SuperMicro 8050. It has three redundant
250-watt power supplies. I can pull two of them out, and it will keep
running - that's with *four* Xeons, a RAID controller, 5 SCSI drives,
another SCSI controller, a gigabit ethernet controller, a 100 mbit network
controller, video, and all the works. If a single 250-watt power supply
will keep that thing fed with power, then I think that most home users would
be very hard-pressed to overload it. I suppose that if they had a 1 GHz+
Athlon, 4 hard drives, and a dual-processor 3DFX card, they might be able
to, but short of that, I doubt it.
