Subject: udma speeds 100 v. 66
Date: Tue, 03 Apr 2001 08:56:14 -0400
Hi there-
We have many systems using Promise Ultra 66 on drives with 66 or 100
UDMA interfaces. Typically speeds on an unloaded system are as follows
on the Ultra66 systems:
[root@nixon kim]# hdparm -Tt /dev/hde
/dev/hde:
Timing buffer-cache reads: 128 MB in 0.86 seconds =148.84 MB/sec
Timing buffered disk reads: 64 MB in 1.80 seconds =35.56 MB/sec
Now, while that's great and faster than my SCSI systems, I don't see
much difference between Ultra 66 and Ultra 100. Here are speeds on an
unloaded Ultra100 system (with a 100 UDMA interface of course):
[root@clinton kim]# hdparm -Tt /dev/hde
/dev/hde:
Timing buffer-cache reads: 128 MB in 0.93 seconds =137.63 MB/sec
Timing buffered disk reads: 64 MB in 1.84 seconds = 34.78 MB/sec
This is (essentially) the same! In setting up each machine, I simply
compiled Promise controller support into my 2.4.2 kernel. Is there
anything nondestructive I can do with hdparm or lilo to increase the
speed of possible both setups?
Also, this probably shows my ignorance, but why don't I get 66 MB/sec
disk read speed on the Ultra66 and 100 MB/sec on the Ultra100? maybe a
dumb question . . .
Thanks,
Ken

I can only use up to version 0.5.10b for my Asus K7M mobo that comes with
via686a chipset. I tried to upgrade to the newest ALSA package, even from
the CVS source tree, and the modules fail to load. There is no problem in
compilation of the package.

LILO release 21.7.3 is based upon Werner Almesberger's LILO version 21.
Version 21.7.3 is a bugfix release.
Version 21.7 adds support for higher serial line rates.
Version 21.6 is an upgrade for users of the Reiser File System, and adds
new diagnostic capabilities. Internal changes allow booting kernels with
larger real-mode setup codes (2.4.0 and later).
Source code is available for download from:
ftp://brun.dyndns.org/pub/linux/lilo (developer's site)
Or from the main distribution site:
ftp://metalab.unc.edu/pub/Linux/system/boot/lilo (please use)
See the distribution file 'CHANGES' for details of the differences between
21.7.3 and prior releases.

in kppp you should find something to add an extra initialazation
string, here you can add the one you found in your modem log file of
windows. Perhaps it helps.

That's strange! I'm using a gigabyte mobo and Linux-Mandrake 7.2. You're
not using RedHat 7.0 are you? I believe there is an issue with the compiler
in that. (ie things appear to compile OK , but don't work!) I believe that
for some strange reason they issued 7.0 with a very beta compiler!
I just downloaded th three packages, compiled them and installed them! A
few tweaks to modules.conf and the install scripts, and it all worked a
treat!

I prefer turning down the rate to about 75. At too high a clock rate
(not refresh rate) the pixels blur and the contrast drops. I like to
stay at about 100MHz clock on a 15" at 1080x800.

one word _EXTERNAL_. yes, i know you said internal but why not expand

Last night I tried to set up Debian Potato on my system last night, and I
found that X would not start because the mouse was not working. I have a MSI
5169 MB with built-in ps/2 ports, and my keyboard and mouse are both ps/2.
What could be going wrong, and how can I fix it? I have checked to make sure
the mouse works under Windows and under Redhat 7.0 without problems. It's a
Logitech Marble Mouse, which works as a standard generic ps/2 port mouse.
I'm not absolutely new to Linux, but I still haven't quite learned how POSIX
systems access devices and what tools there are to check various ports. I
have used XKBSetup or XKBconfig, and despite changing protocols, the cursor
will not budge. Please help.

So you know what not to do! So carry on choosing numbers imbetween until
you find the right value. It's likely that your bios takes a meg or so.
