Lin-Lin + Cel T 1.3 + M754

ahnic · Post by **ahnic** » Sat Jan 15, 2005 8:23 am

Hi,

Sorry for asking PCCHIP motherboard problem on bp6 forum, but
I really need your help or suggestion. I got a Lin-lin adapter and
Cel T 1.3G. When I plug the adapter together with the Cel T to
my PCCHIPS motherboard M754 and power on, it boots up and
shows "Intel Pentinum III Xeon 1.3G" on the screen. Everything
seems OK and I can run real dos text mode program. However
when I starts windows (win98se or win2k), it hangs immediately
with black screen. It cannot even enter the safe mode of win98.
I have already upgraded the BIOS to the latest version and
everthing returns to normal when I put back the orginal 1G
coppermine cel cpu. Do you know how to fix it ?

Thank you very much for your help!

Sorry for double post! Do you know how to delete extra post?

Here are the voltage and FSB settings for the Lin-Lin adapter from our Knowledge Base article.

The following link is a thread about stacking a 1.4 Ghz Tualatin Pentium III processor on a Lin-Lin adapter, which is stacked on top of a PowerLeap NEO S370 adapter and the whole stack is plugged into the BP6.

Maybe this information will point you in the right direction.

Thank you very much for your reply. I have already set the proper Vcore
and FSB on the lin-lin adapter. That's why it boots up and shows "Intel
Pentinum III Xeon 1.3G". However it can ONLY run real dos text
mode program and can NEVER enter into any graphic mode, is it
something to do with the BIOS or chipset?

My first ever "store bought" system was M741LMRT. It is frustrating to say the least whenever any newer hardware was added.

I downloaded the manual to your board from PCCHIPS.com.
It shows that board can take PPGA or FC-PGA1 socket 370 cpus. There are no hardware settings to ID which type of CPU is used. However the BIOS has a page for CPU setup. The text on the pages follows:

CPU PnP Setup Page
This page lets you manually configure the mainboard for the CPU. The system will automatically detect the kind of CPU that you have installed and make the appropriate adjustments to the items on this page.

My board says something simular but there is nothing to change except the FSB and multiplier settings neither of which tells the system you have a Tulalitan(FC-PGA2) instead of Coppermine(FC-PGA1).
My guess is that the Lin-Lin makes the system think it is a Celly-1.(the FC Celly-2 didn't exist at the time the M754LMRT was designed) The Lin-Lins allow it to TRY run as an FC Celly-1 but the software or BIOS gets confused when a more complex process is attempted then basic text output because the Celly-2 enhancements kick in and that cpu throws out results the bios and software don't expect and can't understand.
I doubt the setup can be made to work.

Yes, I agree that the BIOS can't detect the proper new Celly-2 . That's
why it shows "Intel Pentinum III Xeon 1.3G" when it detected the new
Celly-2 has 256k cache which is twice larger than the old celly-1. I guess
this causes the problem. In any graphic mode, the BIOS tries to issue
Pentinum III instructions but the CPU is in fact a Celly which leads to
conflicts. Do you know how to edit the BIOS so that I can force it to
identify the CPU as celly eventhough the CPU has 256k cache?

Thank you very much for your information!

Not me know.

Could someone recomend a freeware tool for editing BIOS? I have a couple boards at home that still work and I want to try hack(at least one until I screw it up).

I've never attempted it myself, but I believe Cbrom is a popular tool to do just that.

Here is a tutorial.

Thanks, I might give it a try. Maybe something simple like just a date change so Sandra will stop telling me to get an update on my old BIOS.

BTW, How can a blank BIOS chip be programed?

Surprise surprise - with a BIOS Programmer!

Jeez, I wasn't asking a trick question, but I guess it was a dumb one.
For a "one time need" instead of getting a rom burner it would be cheaper and more reliable to just buy a programed chip.
Me thinks I remember this issue has already been discussed.

I was only messing with you!

Take no notice.

Some electronics shops have programmers, and one may be persuaded to let you program a ROM from a floppy.

It sounds to me like the BIOS you have is missing the appropriate Tualatin microcode so it can't identify it and can't use it in more than real-mode.

To add the microcode follow the directions here:

http://www.frogge.de/pepper/bmreport1.html

I've done a similar procedure for the AOpen AX6BC and it worked great.

...

Now that I think of it though, your PCChips motherboard probably has an AMI BIOS so these procedures won't work. But, you should be able to find a similar guide for AMI somewhere on the web. To give you a head start one of the programs you want for AMI bioses is called amibcp and you can get it here:

Hope that helps,

Great to hear from you, loophole! Thanx for your input!

Any time

I recently found a BP6 for sale and thought I'd go and check out this forum again. If I manage to get the board you'll be hearing a lot more from me

There aren't very many boards that are in the same class as the BP6:

Legendary

Dual Celerons despite the fact that according to Intel it CANNOT be done - I just love that!! And I've missed my BP6 system so it's time to jump back on the BP6 train

I guess that ends my off-topic rant for the moment (more to come),
loophole.

Thanks for all feedback! Especially loophole, you are right. I am trying
to mod the cpuid and microde of the bios. But before that I will
build a twin-bios circuit for my old motherboard.
