Questions about MPS 1.4

what i read indicates that the apic has an extra byte enabled, but it still takes a multiprocessor operating system to initialize that byte(..pg. 75-78 ).

right after my bios post configuration screen is displayed i get two entries on my screen just before the floppy seek -

BSP 512K CPU Micro code OK
AP#1 512K CPU Micro code OK

thats Boot Strap Processor and Application Processor...given that, windows 98/DOS et. all would only see 1 CPU(..probably BSP). win2k on the other hand initializes that byte and gains access to the other cpu!

one question...is the MPS mechanizim in win2k 1.4? i can't seem to verify that.

Questions about MPS 1.4

Hi Guys,

I need some input here ...

I use several Asus Dual MoBos which all have an entry in their BIOS labeled MPS 1.4 support.

I tried to gather information about that, but all I found were some vague comments and a manual entry saying 'for future purposes - leave on default=disabled'.

...

Anybody out there with some knowledge to share ?

Background is that my latest working rig is sported by two P3-600E, but its performance is somewhat too low.

Thanx a lot !

You should read this then: http://www.intel.com/design/pro/datashts/24201606.pdf

Excellent, Jan !!!

Quite some stuff to lecture ...

Thanx,

It's easier than 97 pages, Maggi

Just because the stupid Search option doesn't work on the Asus pages (why not, btw??), I found this entry for you in their FAQs:

Q & A -011 for P/I-P65UP5/C-P6ND Motherboard

Just don't look at the PentiumPro thing in there, will ya?

Thanx, Jord ... but it's not that easy.

MPS=MultiProccessorSupport ... crystal clear

but as far as I got into the PDF that Jan posted, it seems that this option in my BIOS will enable utilization of both CPUs even when the software is not explicitly written to support more than one CPU at once.

Sort of an afterburner me thinks.

Cheers,
Maggi

An old feature, none but Novell ever tried to utilize, you mean?

Probably your best guess. Have you tried enabling the MPS 1.4 in the BIOS and see what it does to your Win2k or NT4?
