Hello and thank you for reading.
Does anybody knows wich chipset the ATI Mach 64 videocart is using so that I
can properly configure my videocart under Redhat 5.2, now I can only work at
600 x 400 and that's a little to big.....
If possible please respont to my emailadres: [EMAIL PROTECTED]
Thank you for your help.

It would be interesting if you could mount the partitions on your
disks raw (read-only!!) and read the first 32 MB of each, and also
the last 32MB of each, reading all sequentially, with nothing else
going on. Also if you would mention how your disks are partitioned.
Otherwise you are partly measuring the state of your file system and
the performance of the file access software. Which distribution/kernel
are you running? (BTW, are all the disks on the same box/controller?!)
And what is the size of your read blocks?
Not having delved yet into Linux diskio and file system code, I'd say
also - depending on how/when things are queued in the file system and
in the scsi controller, it might be interesting to try two threads
with one reading even buffers and the other reading the odd - if you
can arrange direct DMA into your buffers. What I'm getting at is that
a slower disk can appear faster if the software time from completion
of one read to the initiation of the next is more than the rotation
time between blocks, so you lose a whole revolution on a fast disk
but catch the next immediate block on a slower one, and lose no time.
This should be more apparent if you read small blocks on a controller
that doesn't cache tracks by default anyway. An interesting number
is revolutions/bufferful_read actual vs theoretical - remembering
that data/rev is denser at the outer edge of the disk.
Anyway, a lot of factors. I'm sure others will come up with more.

Subject: 3Com USR 56k Internal modem
Date: Sat, 27 Mar 1999 16:14:02 -0600
I just installed Linux last week and I am still learning.
I had a USR Sporster 33.6 modem with jumpers set
to COM2 and IRQ3. I was able to set this modem up
in Linux with no problem, However I just bought a new
3Com USR 56k Internal modem that has no jumpers, and I cannot seem to get
Linux to see it ? As far as I can tell it is not a Winmodem, and it works
fine under Win98. Under Win98 PNP set the modem up on COM3 IRQ11. I
changed the windows setup to be
COM2 and IRQ 3 like my old modem, but Linux still
does not see it.
I would appriciate any help from someone who has this modem working with
Linux.
Regards,
Troy

The kernel is at /usr/src/linux/arch/i386/boot/zImage. Copy this file to
where your kernel currently is, rerun LILO if you use that, then reboot.
Better yet, if you use LILO, you can compile the kernel using "make zlilo"
and it should do all the copying for you.

Derk,
Unless I'm misunderstanding videocart for videocard and you meaning
something different. The ATI Mach 64 is recognized by RH and you should
be able to get better resolution by ctl, alt +. You can edit your
/etc/X11/XF86Config to make a different resolution the default by
putting it first in the list - the list will have 4 there. Also you can
change the default for colors there in XF86Config.
I forget what the chip is - you'll have to take it out and look at it
but you should not have to do that. You do not need to specify it or
probe for it to configure correctly should you be doing that over -
which is not necessary. All this is for the ATI Mach 64 Turbo Pro.

based on my experience with egcs over the past year, not much.
the pentium classic seems to be hypersensitive to scheduling, but the
i686 (i have a pentiumpro) seems have roughly the same performance
(using time on a few of my programs) for compiles with -march=i386,
i486 or pentiumpro. -march=pentium hurt speed by about 10%.

Why doesn't one of you programming geeks save us all a lot of trouble, and
make the many winmodems that are in Linux machines today more than a piece
of silicon doing NOTHING!!! I am one of those people who just bought a
nice $100 winmodem (not knowing it WAS a winmodem) and finding out that it
is useless in Linux. In fact, I will PAY someone to do this and have the
driver distributed throught the net so we can have them adapted to fit all
winmodems. If someone does this, or has any ideas or problems...please
email me @ [EMAIL PROTECTED]!!!

I have a Western Digital Drive on my RedHat 5.2 and it works flawlessly, no
special setup. However...
1) It depends on how recent the motherboard BIOS is...
2) On *MY* system, there is no dual boot, it's just Linux. (Network Server)

Use a Tulip-based card. A couple of speed improvements in the 2.2.x
kernel work on tulip cards but not necessarily on any others (yet).
Linksys markets such a card called the EtherFast 10/100. It's RJ-45,
it's PCI, it's well supported by Linux, it's super fast, super
reliable, and it's about $25 at Fry's.

Wait a minute, you've got the 50-pin-connector drives? In that
case I am quite confused. I did not think the NCR driver could become
that confused. Learn something new every day I guess...

Not all people operate that way. :-)
Given that my workplace is a Mac, Windows, and Solaris shop (in terms
of the desktop), cross-platform applications are something that might
get looked at quite a bit.

I got cdrecord to work with my HP-7200i (or maybe it is an 8100, but
it is IDE and HP and internal).
I used an unpatched 2.0.35 kernel (since 2.0.36 wasn't out then). I
did need to follow the directions regarding turning off the regular
(non-ide-scsi) IDE CD-ROM driver (so I did need to build the kernel
rather than just using a prebuilt one). Don't remember a lot of
problems other than that.
Don't know about 2.2.x but at least for a while, 2.0.36 (and other
recent 2.0.x releases were ahead of 2.1.x in terms of having the
latest drivers). Like I say, I don't the situation in this particular
case.

I've never heard of DosLinux but with most Linux distributions you
just pick "ne2000" or "ne2k" or something like that from the list of
ethernet drivers (details will, of course, vary somewhat by

Here's an idea, Cameron; why don't _you_ program the driver? If it were
so easy to do, don't you think it would have been done by now? After all,
Winmodems have been around for quite a while now. Or, you could bring the
Winmodem you bought back to the store and buy a hardware-driven modem. It
was _your_ mistake, anyway.

Don't know about Abit, but on ASUS there are some I/O ports (that is,
accessible via the outb and inb instructions (I think that is what
they are called)). You can actually do this from a user program
(which runs as root, there is a system call, I think it is iopl(),
which lets you access I/O ports). However, in many ways writing a
driver (which goes in the kernel) is cleaner.

This will be good for how to make a driver (for example,
/proc/temperature - start with /proc/hello-world just to make sure you
understand it).
You'll need to find some Abit doc (try the abit web site or
alt.comp.periphs.mainboards.abit) concerning the details of how
to access the Abit hardware.

Nope. 68-pin connectors. Does a 68-pin connector imply a 16-bit word
size even if the drives are listed only as Ultra2 drives (not U2W)? I
was under the impression that Ultra2 meant an 8-bit word size at 40mhz
while Ultra2Wide meant 16-bit. Could be wrong, though, as this is my
first venture into SCSI-land since 1985 with my Apple ][gs (which barely
counts as SCSI, but I guess technically it was).
