VMWare will not run on kernel 2.4.0-test11

VMWare will not run on kernel 2.4.0-test11

[Phil Stracchino]

I just compiled and installed kernel 2.4.0-test11.  Upon rebooting,
vmware-2.0.3-786 refused to run.  Running vmware-config.pl resulted in a
the following message:

	"Your processor does not have a Time Stamp Counter. VMware will
	 not run on this system."

Since (1) my hardware has not changed, (2) this VMware release ran
perfectly on 2.4.0-test10, and (3) I changed nothing but the kernel in
between 2.4.0-test10 and 2.4.0-test11, I feel quite confident in believing
that I do indeed possess a Time Stamp Counter (whatever such a fabulous
beast may be), but for some reason VMware is unable to detect its presence
when running on kernel 2.4.0-test11.  Evidently there has been some change
in the kernel which renders VMware unable to detect this mysterious - but
apparently crucial - feature.


I would appreciate any insights from either kernel folks or VMware folks
as to where this problem may lie, with an eventual aim of patching either
VMware or the kernel to allow VMware to run on this kernel.

Thanks, Mohammed!  That was fast.  :)

It's probably due to /proc/cpuinfo change - 'flags' has changed to 'features'.

Yes.  All the BIOS does is configure your hardware.  Get docs on your
hardware, and you can do anything that BIOS does.  For example, if your
parallel port is disabled in BIOS, and you have the datasheet for your
southbridge, then you can "manually" enable the parallel port by writing
certain values to certain PCI config registers.

That said, it is generally a bad idea to do this sort of thing.  Unless
you have a cluster full of machines that all have a BIOS-related
problem, or similar, you should just reboot and adjust your BIOS...

Of course, if you are really motivated, you could just flash your own
BIOS.  Check out http://www.acl.lanl.gov/linuxbios/

	Jeff

changing BIOS setting

[Andrew Park]

Hi,
Is there a way to change BIOS setting (like boot sequence)
from the kernel space?  Any pointers would be appreciated.
Thanks

Re: changing BIOS setting

[Chris Wedgwood]

However , this won't change boot sequence at that is store in the
CMOS on your RTC chip... if you really wanted though; you could mess
with that via /dev/nvram or whatever it's called.

Not that I suggest this is a good idea, most likely you will corrupt
it and the BIOS will get a checksum error and reinitialize the nvram
to defaults.
