I'm not a Linux expert, but I believe that Linux 2.2 can only handle 4
IDE buses, and you have 6 (2 ATA100, 2 ATA66 and 2 ATA33 on the
motherboard). so when it checked for IDE, it got to the ninth drive
('i' is the ninth letter of the alphabet) and choked. You'll need a 2.4
based install package, or disable/remove one during setup until you can
build your own 2.4 kernel.

I have a 3c905 and a 3c595 network cards in my computer.. I used to
have a p2-266 but upgraded to a p2-350.. Everything used to work great
but now,,,, The 3c595 card goes to my dsl modem.. Works great.. The
3c905 goes to the intranet.. Doesnt work great.. When I ping a site on
the internet.. Everything is fine.. When I then ping a computer in my
intranet.. The pinging of the outside site stops and the inside pinging
loses most of the packets.. only some return.. I did notice that both
the cards are using irq 12.. Any ideas on this one...
Heres the boot messages..

And so it is. There is no support for that driver in the installation
kernel. Plug your drives into the standard IDE interface sockets
instead.
When all is installed, compile a kernel with the right driver, and plug
the drives back where you found them first (etc.).

Subject: How to detect Hardware with shell commands.

Reply-To: [EMAIL PROTECTED]
Hello,
Are there any commands to detect Hardware config under linux (using shell
programming like bash/sed/awk/dd/cat/$()/proc/...)?
I'm aware of /proc/pci for example(lspci isn't present everywhere), but I
don't know how to detect the number of SDRAM modules or the speed of SDRAM
modules (are my 256Megs == 2*128MB 133MHz SDRAM or == 4*64MB 100MHz SDRAM)
I'd like to detect physicals PCI busses (there are pci boards that are
parts of the mainboard).
I'd like to detect CPU Bus speed.
I'd like to detect PCI width and speed (64/32bits 33/66MHz)
I'd like to detect free physical pci slots. (or vesa or isa too if possible)
I'd like to detect if I'm running on battery or on sector
I had a look to /proc, but maybe a dd if=/dev/kmem with appropriate
parameters would allow more infos?
(My aim is to create a multi platform exploitation document generated in
HTML. Actually, the SUN/Solaris and Compaq/OSF1 parts are ok :-).)

If you want a quick & dirty "map me my device" then just
do an mmap call on /dev/mem giving the physical range
that you want to map (you can find your device via "cat /proc/pci")
and using the returned virtual address as the base of your device's
memory range. This is a hack, but you asked for "the simplest way"
and that's what this is.
Note that the usual permissions on /dev/mem prevent all but root from
creating writeable maps on /dev/mem).
x86 note: This is assuming that you're in fact talking about a PCI
device's *memory* range, not an i/o port range.
x86 note: If you want any sort of decent write performance
(above about 30MB/sec) to PCI device memory space on PII's or
later then you'll have to write a kernel module and mark the appropriate
portions of your device's address space as USWC via the mtrr_add() function.
Beware: make sure you understand USWC before doing this, because memory
transactions to USWC memory are "weakly" ordered.
General Note: make sure you understand the memory ordering rules of your
host platform, this is especially crucial when accessing PCI device
addresses
that have side effects. Usual problems are: multiple writes to the same
address could be squashed by the processor, or writes can arrive at the
device in a different order than the order they were issued by the program.

In the comp.os.linux.networking group, someone mentioned
that there are timing problems with the 2.4.0 version of this
driver. I suggest you try to use the 2.4.1 (release) version of
the driver - it was claimed to have been fixed in this release.

I can see this as an improvement to be able to burst faster, and be done
with it, but there are still problems that a single cable/channel (with
2 IDE drives) would have. If a single channel is used with two drives,
IDE does not disconnect and allow the other drive to use the cable while
the original unit is executing its instructions (whether that is to
fetch or write data). So each drive must access the bus sequentially. If
that data is cached in the internal ram, the 100 MHz burst would be very
good (not as good as Ultra 160), but on read of a large amount of data,
there is no way that the cache can help nearly as much as for smaller
reads. Despite the great improvement of ATA100 over earlier IDE, if
separate channels are not used for each drive, there is a great
disadvantage for IDE versus SCSI. Add to this the extra cpu overhead of
IDE (which can be greatly reduced by DMA operation), and the advantages
drop or gain much based simply on the cpu speed. The really nice IDE
solutions, for raid boxes, put a separate controller on every IDE slot,
and possibly coprocessor to relieve the main cpu from the overhead (in a
way this is hardware already on each scsi disk). All of this is to say
that results for software raid will generally be much better for scsi;
it is possible to obtain good results for IDE, but it is more difficult,
and not as easy to predict.

Tape devices don't use file systems so you don't mount them.
Just read and write the data directly to the device.
