i was benchmarking mainly with aida, 3dmark2001, sandra in addition to real-time performance in very old games. i was tweaking the chipset register settings(dram access before snoop complete, memory burst refresh, disable onboard vga shared memory etc) , adjusted memory timings and observed the impr...

Re: Need to patch PCI configuration table in Award BIOS 4.51

hi, your mainboard's bios has lot of code-wise similarities to my motherboard's bios. but the platform and chipset are entirely different. i'm trying my best to understand the issue. will update if i find something. meanwhile if you happen to come across the datasheet of this chipset (VT8378/VT8237)...

Re: incompatibility b/w old motherboard and new graphics car

i could not update earlier. i inserted the modded bios components in the wrong order by oversight, that's why the MSI mainboard wasn't booting. i took the services of local shop for re-flashing, reapplied the same technique and got it working with the MSI mainboard too. i'm now sure that the new gra...

Re: Need to patch PCI configuration table in Award BIOS 4.51

I'm not an expert or something. but I can give it a try if it is not much different from mine that I recently disassembled. which bios version are you using? Can you send the disassembled bios so that I can continue from there?

Re: incompatibility b/w old motherboard and new graphics car

i'm very happy to share that at last the card got detected by one(ECS P6STP-FL) of the two old mainboards(other one is MSI 6368) i have, after introducing a delay at the time of pci enumeration and a patch in awardext.rom module for properly identifying 64 bit prefetchable memory requests by a pci d...

Re: incompatibility b/w old motherboard and new graphics car

hi, i found one more probable cause for the poor performance. as i'm manually assigning values to the graphics card's BAR's and PCI-e to PCI bridge memory and prefetchable ranges(after booting to DOS), the MTRR's for these ranges are not defined in the host's address space as WC or WB. it is by defa...

Re: incompatibility b/w old motherboard and new graphics car

hi, this graphics card(nvidia GT 520) was properly detected in a P4 system which also had a 32 bit PCI bus only. the 64-bit issue i mentioned pertains to processor's memory space and not that of 32 or 64 bit pci bus. anyway the issue i mentioned doesn't look like the cause of the incompatibility. i ...

incompatibility b/w old motherboard and new graphics card

hi, my old P3 mainboard bios was not properly detecting a modern PCI graphics card(with a PCI-e to PCI bridge) and it doesn't turn up in the pci device listing during bootup. on diagnosing with a DOS tool, the reverse PCI-PCIe bridge (Pericom chip) onboard the graphics card was not passing on the me...
