Ok. I'm fairly new to overclocking graphic cards, but this is the first time ive ever killed a card...or so i thought
I recently purchased an ATi Radeon X1950 Pro AGP 512mb [Sapphire]. After google'ing around i found a lot of other people running X1950's at higher clocks, Me personally, Right now I'm running stable at 600/715 [Default 580/700]. Anyway, I should have quit there, but no. I found some people saying that their Sapphire X1950 Pro AGP BIOS needed to be updated or they were purposely updating or modding it for overclocking purposes.
So after seeking out BIOS flashing info and tools I eventually ended up with RaBiT 2.2.0, ATIWinFlash and ATIFlash, I already had ATITool [0.27b2]. Now I've flashed my mainboard bios before and i understand its a risky procedure, but all X1950 BIOS's are the same right? Wrong. BIOS's as far as i know contain info on voltages and default clock speeds. Not sure if it contains interface info [PCI/PCI-E/AGP], but I'd imagine it does. Anyway VERY IMPORTANT
Backup/DUMP/Save your BIOS using whatever means works best. Be it RaBiT or ATITool or i think even TPU Has a Bios Saver.exe util that i used too :P The bios i ended up using to save my card was this very bios that i dumped before i started to screw with it.
My error, I ended up flashing my X1950PRO AGP 512mb card with a BIOS for a X1950PRO PCI-E 512mb. I did this flash with ATIWinFlash 126.96.36.199 as well. Probably not a good idea either.
After this of course my card was effectively dead, Black screen on boot. Just about everyone has on board lan/sound/video these days, so naturally i tried using that. Nope, Had to clear the CMOS on my mainboard [ECS P4VMM2 Rev 7.3] I'd imagine this is cuz i either had my on board video disabled as i might have done when i got the card, dont remember :P Anyway thats what i had to do, If your at the black screen and cant boot stage of a bad flash, try clearing your CMOS/BIOS [for me this was done via a jumper, you probably have one too, check your manual]
After clearing my CMOS and using my on board video im back up and running, but the card is still dead, not detected nothing. This is where it all starts. After downloading just about every version of ATIFlash for DOS and trying a couple windows versions as well the card is still invisible. As of posting the latest version of ATIFlash is v3.49, DONT use it. It always crashed out for me. Try it if you must, But I'd suggest getting v3.15
Apparently it is a very very good idea to flash from DOS, unfortunately Windows XP doesnt exactly have DOS. Now, some of you might even have an old school 9x Boot Disk lying around. Thats great, I dont even have a floppy drive [well i do, but i never hooked it up and its collecting dust in my closet]. So I'm going to route of USB Keys and Bootable CD's
Now this is probably the 2nd day into my X1950's coma. Regret and stress is x2. Now assuming most of you are running XP, dont know anything about rebuilding bootable images and certainly dont know much about DOS and Filesystems and NTFS/Fat32 and (in)compatibilities or that...oh i dunno maybe the fact that DOS cant read your NTFS XP Partition.
Luckily for me I had this wonderful collection of tools called the 'Roadstarter Boot CD' or Ultimate Boot Disc. Find something that looks like that and burn yourself off a copy. This CD is an absolute god send for what i had to do, its also just handy for tons of other stuff too :P
The RSCD [RoadStarter bootCD] has a great assortment of options and pre-made configs for booting into DOS with support for things like reading USB Keys, CDROM's, ZipDrives and yes NTFS HardDrives. The option that worked best for me i believe was DOS -> DOS-No EMM386 used in conjunction with NTFS 4 DOS 1.3 or something like that. Dont use HIMEM or EMM386 and avoid RamDrive if you can, but i believe it worked with RamDrive on as well. I ran into a lot of delays here cuz not only do the latest ATIFlash versions require more memory [DOS is a very limited enviroment, especially in this scenario] ATIFlash v3.15-3.2x ran for me in cases where 3.4x wouldnt run cuz of memory issues.
Anyway, Provided you can get into DOS and get the tool running correctly this is when you'll run into the 'Adapter not found' and Error 0FL01 messages. Which is probably what brought you here which is probably where your at. [just being thorough, i want others in this situation to be able to revive their cards!]
!!INTERGRATED/ON BOARD VIDEO DISABLES YOUR AGP SLOT!!
Unfortunately this was the case for me, not sure if its like that for everyone, but...logic tells me it would be. You may have read that you can revive your card by reflashing with a PCI card. However PCI Cards are quite old and not really the mainstream anymore, Lucky for me, I had one lying around :P So to revive an AGP Card you need a PCI card, ANY PCI card.
After getting the PCI Card booted my AGP Started showing up in my POST as IRQ 5 listed under my PCI Devices, this is another way to tell if your card is detected so keep an eye out for it. ATIFlash -i started detected my card fine and the flash went fine as well, well...not exactly. I tried a bios provided by Sapphire for X1950 AGP cards with fan issues, but it didnt work. Oh well, the original bios did. I'm not complaining. [and i dont have fan issues]
I hope this post has helped you
