I've got the latest APC UPS and it has a USB port!
Has anyone got this to work?
Now this is something that USB is good for ... if it would work.
Thanks,

Subject: Performance problem IBM ATA100 drive, SiS 5513 chipset
Date: 26 Sep 2000 11:02:45 +0800
I have a system with an ASUS P5S-B motherboard (SiS 5513 chipset,
AT M/b) and an IBM Deskstar 75 drive. The CPU is an AMD K6-II/500
(and reported as such by the kernel).
The drive is capable of something over 30 Mbytes/sec off the surface,
and the board is supposedly UDMA/66-capable..
According to hdparm actually get somewhat less;( - More like 14 Mbytes/sec.
root@dugite /root]# uname -a

[root@dugite /root]#
Performance with 2.4.0 kernels is pretty much the same, with and without SiS support.
. I've applied all the hdparm tweaks I think might help (without them, 4 Mbytes/sec is
a struggle):
root@dugite /root]# hdparm /dev/hda
/dev/hda:
multcount = 16 (on)
I/O support = 1 (32-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 3737/255/63, sectors = 60036480, start = 0
[root@dugite /root]#
I have another (lower-spec) IBM drive on another system - PII, LX chipset.
It runs at close on 17 Mbytes/sec off the disk, 64 from cache.
The questions that come to mind:
1) Is this chipset actually capable of performing at UDMA/66 speeds?
2) If so, is this board crook?
3) Are there better boards (remember, I must have an AT card)
If the chipset/board are capable of performing at UDMAN/66 speeds,
then what must I do to get it?

I tried just using the ide-scsi module but it only finds one of the two
drives. Perhaps I should disable the Check all Luns option in the SCSI
support.

Do you have any other parallel ports or parallel devices? I have a 540 and it
needs to be on the mobo parallel port alone to work (ie. no scanners or webcams
in line).

First, note that reset is not part of the problem, but is actually the host device
driver trying to recover control of the bus after the problem already exists.
Since the drive is that old and the host adapter is that new, perhaps it is a
timing issue.
In the host adapter BIOS, turn off all the special features, like SYNCHRONOUS,
WIDE, DISCONNECTS, and the other optional stuff for that unit ID. By eliminating
the specials, the drive will operate in the original SCSI transfer mode, which has
a better chance at compatibility.
This will make that device a little slower, but you don't seem to care about that
sort of thing.

Try the command : cat /proc/interrupts for irq usage or cat /proc/ioports

The kernel sources should be included in the distribution.
Maybe you did not install them. IIRC, the SuSE installation
process does not install them by default. You can easily
install additional packages using the (old) YAST1 setup
tool.

Hallo James, I don't know how big is your harddisk. But I make a good
experience with 2 GB. The normal setup eats ca. 1,2 GB of your disk.
Don't worry about LILO and the disk cylinder. The LILO version in
Mandrake 7.1 can cope with more cylinders. If you like a pretier
Bootmanager then you can try GRUB. Mandrake will ask you to choose at
the end of installation.

It wouldn't be unusual for it to be bad ram, or an overheated chip with
overclocking. If you overclock, or have set your bios wait states too
short, try backing off some. If you have ram in more than one slot, try
using only one stick at a time. You may also wish to remove extra cards
during initial install, such as the sound card, adding it later if it
works.

Yes, I have one of these (actually the 2976, but it makes no difference in
this case).
The easiest way to make it work is to download and install:
serial-5.04 [actually v. 5.05 is now available]
from sourceforge.net.
After you unpack and install, just reboot the system and the modem should
be recognized.

James is right to worry about the number of culinders; my 30 Gbyte drive is
definitely too big to be unpartitioned. However, LILO (and more importantly,
the BIOS) can be kept happy by making a /boot partition of 16 Mbytes or so.
I also have an 8.6 Gbyte drive that can't be booted (I got caught) unless you
take precautions.
If your installer gives you the option to make a boot disk during the install process,
take it. Better safe than sorry; getting a Linux system up when it won't boot from the
HDD
is not a task for a novice.
After boot, there's no problem with parition locations or sizes.
For partition sizes, read your manual;-)
I do recomment you make /home a separate partition - it's a matter of space management.
However, it's not critical - you can install everything into one partition
(subject to 1024 cylinders); later you can add a new drive, copy everything from
/home to it, moun the drive as /home and all is well. No drive letters get changed,
everything's in the same place.
Oh.
Do record your partition information on paper (sfdisk -l | lpr) and print your
/etc/fstab.
In the event you need to restore your root filesystem or whole drive (as I did last
week - dud
drive), you will need the information.

Xfree86 is flexible. You can configure it for this, though the standard
configuration tools may not know.
If you have RHL 6.2, there's a couple of ddc utils part of anaconda) on
the install CD that might help; one produces a bunch of modelines.
RHL 7.0, just out, is supposed to do even better.

Yes - the crusoe chip "emulates" the Intel ix86 instructions and translates
them to VLIW instructions, so the software layer can act as though it is
talking to an ix86 chip.
