Hi all.

I built my own board based on MAX 2.
On the second revision of my board a have replaced realtek LAN to intel 
By now i have issue.
If i build 94 version of firmware in 64 bit mode everything is okay.
If i build firmware using 32 bit mode there is some problems.
In main BIOS setup screen there is no board information in left upper 
corner of the screen.
Also when using windows software(AIDA etc) to identify board 
manufacturer it shows me nothing. No Manufacturer ID no board ID and 
even no CPU microcode revision.
I did some investigations and found that when firmware runs in 32 bit 
mode it does not enter MiscSubclassDriverEntryPoint function which calls 
function AddSmbiosManuCallback which initialize Platform information 
using mPlatformInfo variable.

I tried earlier versions of firmware and results is same.

There is no problems in 64 or 32 bit mode on previous board with realtek 
LAN. This is only difference.
