A good place to start would be to check out BYTE magazine's web site. They
have made their BYTE benchmark suite available free to anyone who wants it.
We use this suite as a part of our ATS testing and have found it to be a
good measure of performance (for what it tests, we test a whole lot of other
things as well...)
In general, any sort of UNIX benchmarking suite should be readily
recompilable to LynxOS.

I also had trouble using Loadlin *before* Win. Had to do reboot to DOS
after windows before LOADLIN. Never did find out why, though, but perhaps
this was due to my HP 7100+ CD Writer which required initialising before
Linux would recognise it, and unfortunately it was the drivers in Win which
did this (Don't have any trouble with an 8100 though)! This was just a
plain vanilla P166 64MB machine with *no* P&P cards or anyhing else weird.

A workaround I used to use is to mount the cdrom so that you can
access it from your ftp server. Then you tell dselect to use that ftp
as the source. You get the best of both worlds.
I'm sure someone who actually understands dselect will know the real
solution though.

Subject: Glibc compiled but fails test
Date: 11 Feb 1999 16:49:57 GMT
Hi there,
Glibc-2.1 seemed to compile fine with egcs-1.1.1 (not the latest
snapshots, which also produced buggy kernels), however, during
"make check" I got the following problem in the nss directory:

Any ideas where to look for a misconfiguration? This is a stand-alone
machine not connected to the net, but with a network card. I didn't
see an option to disable nss during configuration, but there may be
such a possibility. --disable-nls wasn't listed either, but didn't
produce complaints.

Sorry, but thats not correct:
A inode is owned by exactly "one" file. Every file on an file-system has it's own
inode (See the ext2 implementation in /usr/src/linux/include/linux/ext2_fs.h for
details).
The blocks on the hard-drive are accessed through pointers in the inode struct:
__u32 i_block[EXT2_N_BLOCKS]
These pointers can be direct pointers->direct blocks
pointers to pointers ->indirect blocks
pointers to pointers to pointers ->dind blocks
..
So if all blocks accessed through these pointers are not next to each other,
then the inode is non-contiguous.

The answer is 12 meg. The installer checks for 12 (actually 11.96meg) to
install. After that however, the ntldr checks for 8 meg and refuses to boot
with less then that.
The lowest configuration that I have ran NT 4 with Office 97 on was a
Pentium 100 with 8 meg ram. Fairly slow. Fast enough though to run network
services. If you had an extra Pentium around with 8 meg ram it could
feasibly be used to run a mail server or something like that, as long as you
didn't have to many users hitting it :-)

You say that vold is a majestic pain in the ass if you want to access
the raw device. Could be. But some people rarely need to access the
raw device. And that would be even less the case with cdroms.
Those who mainly need the raw device could just forgo launching vold
at startup.
The point is that it should be unnecessary to mount/umount a removable
media if the OS is capable of detecting insertion/ejection of media.
Perhaps we should not be overly concerned with floppy drives because
they are quickly becoming obsolete anyway. For small files, modem is
more convenient. For large files, Zip/Jazz disks or cdroms are more
useful than a boxful of floppies.

Look in /src/examples/apps/src - there is example code that
demonstrates several methods for IPC which can be used for some besic
benchmarking on IPC and context switching.
>Is there free source code that can be compiled?
Well, you have LynxOS, so look at 5922.ats_src.tar.gz in the
tar_images directory of the distribution; this is the Automatic Test
Suite used by Lynx, which includes the "BYTE" benchmark and some
other things you might find interesting.

Hi,
i tried the new and famous kernel 2.2.1 on my alpha
(Samsung UX2 Board, Ruffian, 256MB RAM) and configured it
without loadable module support since i don't need it.
This is the last thing it tells me:
starting kswapd v.1.5
parport0: PC-style at 0x378 [SPP,PS2,EPP]
Unable to handle kernel paging request at virtual address 097ffce0
swapper(1): Oops0
and then a lot of hex values and a register dump.
Does anybody out there have any good hint/idea?
Thanks in advance,

These symbols are defined in the file soundcore.o which when using modules
should be in the same directory. This makes me believe that you haven't
run depmod. Which distribution are you using? Atleast RedHat does it
automatically during boot.
Anyway you might want to do this in a root shell:
depmod -ave
And look closely for any undefined symbols.

I have a Toshiba 220CS which might have the same chip: OPL3SA1? (completely
different from just OPL3) Incidentally the new 2.2.x has a driver for this
card directly but I haven't gotten it to work. Even the MSS driver complains
about IRQ conflicts but it works.
/etc/conf.modules:
alias sound ad1848
options ad1848 io=0x530 irq=11 dma=1 dma2=0
And make corresponding changes in the BIOS setup.

This kinda happened to me on 2.2.1 using umsdos on an 2940U2W AIC7895
chipset just last night. All of a sudden I had a corrupted directory
with FAT errors only in the /usr/src/GCC where I was building files.
Even after rebooting and the system ummsyncing it still had the same problem.
I then booted into DOS and ran c:\dos\scandisk to repair the system aand
it had lost clusters, invalid filesizes or structure, multiply linked
clusters. After some fixing, and deleting of directories and files
by scandisk since it couldn't repair some of it, I ran c:\dos\defrag
but eventually to would crash saying internal error #2, that I had to
run defrag /skiphigh. I ran with /skiphigh but then defrag complains that
it has insufficient conventional memory ( I have 128megs). In the meantime,
I had to rerun scandisk to repair and delete some more files again. I kept
doing this until defrag optimized all the clusters and then crashed on the
last one. I can't do anything about this anymore. Now I probaly have nothing
left of my linux system due to all the deletes by scandisk since it can't
repair some of them.
Note: My doslinux is running on logical partition sda6 (drive e:), whereas,
the dos operating system is on physical drive c:\ sda1 partition which wasn't mounted
- only sda6 was for doslinux to run.
Well, time to reinstall doslinux if it doesn't boot.
