Some time ago, Intel detected a bug related to a wrong dynamic video ram assignment (DVMT) on its GM965 chipset. This affect several Dell Notebook using the GM965 chipset and VBIOS version 1466. To solve the issue, Intel emitted a new VBIOS version 1588, which can be found in many official drivers. The VBIOS must be combined with the system BIOS by the system or motherboard manufacturer before it can be flashed. Based on that, Dell emitted the following BIOS updates: Dell Inspiron 1420 A09, Dell Inspiron 1520 A09, Dell Inspiron 1525 A09, Dell Inspiron 1720 A09, Dell Latitude D530 A07, Dell Latitude D630 A12, Dell Latitude D830 A13, Dell XPS M1330 A12, Dell Vostro 1400 A09, Dell OptiPlex 330 A15. That left the Vostro 1500 behind. The symptoms: This bug causes memory corruption with a lots of blue screens (BSOD). Also, copying or compressing very large files (500mb to 1gb) can end on a corrupted file or unrecoverable ZIP file. I have tried many Vista x64 and Windows7 x64 drivers, and even they seem very stable, somehow still have the bug. My last hope is trying to make a Mod BIOS, with latest DELL A06 BIOS and the VBIOS update from Intel. Is this even possible? I have no experience in Mod Bios, but I'm a fast learner. Please, any help would be very appreciate, I have lost all faith in DELL.
