mmm Posted December 5, 2006 Report Share Posted December 5, 2006 Looking for 4.17.00.55.B4 BIOS for GeForce4 440 Go 64MB found in Dell Inspiron 8200 and Latitude C840. I got this card as a replacement without drivers, so I tried the drivers at Dell.com, which required BIOS A06, so I tried to update with 4.17.00.55.C1/2 provided by Dell and found out that it's not compatible and no backup was made :) Symptoms: display shows white dots at random places, garbage in text mode and Windows load vga-safe drivers. Anyone willing to help to a backup-less looser? :) Quote Link to comment Share on other sites More sharing options...
mmm Posted December 7, 2006 Author Report Share Posted December 7, 2006 I found a friendly guy on the internet who dumped the BIOS off Latitude C840 from working Linux for me. I am attaching the file which worked for my card nVidia GeForce4 440 Go DEV_ID 0174 (with 64MB): 01:00.0 VGA compatible controller: nVidia Corporation NV17 [GeForce4 440 Go] (rev a3) (prog-if 00 [VGA]) Subsystem: Dell Unknown device 00d4 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop+ ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 248 (1250ns min, 250ns max) Interrupt: pin A routed to IRQ 11 Region 0: Memory at fc000000 (32-bit, non-prefetchable) Region 1: Memory at e0000000 (32-bit, prefetchable) Region 2: Memory at dff80000 (32-bit, prefetchable) [virtual] Expansion ROM at d8000000 [disabled] Inside the file you will see: NV17 MOBILE VGA BIOS Version 4.17.00.55.B4 Chip Rev A2 Random notes: 1) the revision seems to be different from mine (A3), but I did not see any problems so far 2) my card has Samsung video memory (versus earlier toasted Infeneon memory) 3) http://linuxbios.org/VGA_support describes how to dump video bios in linux. 4) to get nvidia_agp kernel module working with all 3D blows and whistles with nVidia's driver, I had to move away intel_agp.ko 5) to get 1600x1200 resolution properly working I had to override edid with yet another image.. 6) dam, it's so complicated with nVidia versus open-source ATI, never ever buy nVidia unless they release opensource drivers.
