SubjectBIOS problem, pro Microsoft, anti other OS
To Maintainer:
PCI SUBSYSTEM
P: Martin Mares
M: mj@suse.cz
L: linux-kernel@vger.kernel.org
S: Supported

This alert should probably be forwarded to Others, but appropriate
subTask persons in the kernel-source Maintainers list were not obvious.

Briefly, documented below is the fact/complications that some PC BIOS
chips are now coming with a default Microsoft setting, which makes them
hostile to some functionalities of other OS. If particular under Linux,
a PCI Winmodem did NOT function with the Win98 BIOS setting, but did
fine with BIOS choice "Other OS". Possible, other PCI devices under
Linux OS might be simmilarly afflicated.

This indicates a need for Linux install software to be equipped with a
utility to probe the BIOS and report back "Linux hostile" BIOS
settings. Today most Newbies are getting new PC boxes equipped with
WinModems. Hostile BIOS settings will block their capability to get
on-line. Unfortunately, I do not have the technical capablity to
directly contribute. Thus please forward this alert to however may be
capable and concerned with dealing with the problem.

Subject: Device or resource busy : SUCCESS !

Well, my very sincere thanks to all of you. It works.

DETAILS:
I purchased a Gateway Solo 2550 in September, comes with ActionTec PCI
56k
modem (Lucent chip vendor 11c1, device 448).
I tried the 568 ltmodem: device or resource busy,could not guess why.
cat /pro/pci would show no interrupt
Then ltmodem 578 was made available: same problem.
But then the PnP issue at boot came again last week.
I had tried several times to discover the option in my BIOS setup.
This morning I found: in the "advanced" page there is an "Operating
System" option, to be set to "the most frequently used OS". I had left
it
as Win98/2000 (as I received the machine).
I just selected OTHER.
Lo and behold, ltmodem.o loads without a flaw, I then had a short dumb
terminal session with minicom, and am now connected at my first attempt
with ppp, having already used X11, ssh, and Netscape.

So, again my deepest thanks to all of you on this list, and the bottom
line for newcomers:

IF (Device.or.resource busy) CHECK YOUR BIOS.

By the way I am running RH-6.1, kernel 2.2.12-20 (CERN "official" Linux
distribution). They are on vacations now, I cannot check at this time if
their version of ppp is "generic" or reworked.

Subject: Crippling BIOSes

Folks,
Given Jacques report, it would be good to set up a
diagnostic for BIOS which have such Microsoft/Other choices.
Mine does not.
For those of you who have such BIOSes, please
1) Do boots under both choices
2) Under microsoft do:
dmesg > ms.txt
3) Under other
dmesg > other.txt
4) diff ms.txt other.txt
and report the differences to the List with the name of the BIOS.
If would clearly be desirable to equip future Linux kernels/software to
give a warning about the crippling microsoft option,
which may hamper other PCI harware under Linux as well.
MarvS

CC: discuss@linmodem.org
Gateway Solo 2150
Phoenix BIOS version 17.50
BIOS Page "Advanced"
BIOS Field "Installed O/S" may be "Other" "Win98/Win2000" or "Win95"
Did not try "Win95"
Default was Win98/Win2000, dmesg file attached is ms.txt
Changed to "Other" , dmesg file atached is other.txt

Linux kernel 2.2.12-20

SOUND:
CONFIG_SOUND set to "m"
Using OSS driver (ES-1371 not supported by RH-6.1 2.2.12-20
distribution)
Using PPP version 2.3.10-3

Everything works fine (ppp sessions with sound) once BIOS O/S choice
set
to OTHER.

I repeat what my problem was:
-could not load ltmodem : "Device or resource busy"
-cat /pro/pci did not show IRQ, not even the word IRQ, for Lucent modem
-setting BIOS to OTHER instantly made everything work.

Unfortunately, there is nothing obvious (at least to me) in the above
diagnostics, that would serve to signal the Linux Hostile, Win98 BIOS
