About HD 4870 flashing confusion

[BAGZZlash]

Maybe you heard about problems flashing 4870 cards.

The problem is that the 4870's BIOS is 128 kB instead of 64 kB in file size. ATIFlash, WinFlash and GPU-Z 0.2.4 and earlier however read out the first 64 kB only. So, the file you get this way will be corrupted. Flashing such a file (modified using RBE or not) to the card will prevent the system form booting.
Before flashing a 4870 BIOS (or even before loading such a file into RBE), please double check if the file has the correct size of 128 kB. If so, I wish happy modding using RBE! ;)
All 64 kB-sized 4870 BIOSes in the TPU database (http://www.techpowerup.com/vgabios/index.php?page=1&architecture=ATI&manufacturer=&model=HD+4870&interface=&memSize=0) have been deleted. There are correct 128 kB-sized BIOSes there already if you need.

I just downloaded a bios for sapphire4870 from the database and its 64 kb. (20th July)

There are 2 sapphire 4870 bioses listed, one is 64 kb and the other one is 128 kb.

Yeah, that's right. This one (http://www.techpowerup.com/vgabios/17490/Sapphire.HD4870.512.080609_1.html) seems to be corrupted. Gotta tell W1zzard about that. Thank you! ;)

Hi again, BAGZZlash, I flashed my bios successfully but while i was looking around i checked a few more of the 4870 bioses and there are a few more 64kb bioses there. The Gecube , Visiontek, Powercolor, one of the ATI bioses are all 64 kb. Can you tell W1zzard about those too. Thanks.

Yeh because it changes the fan settings in the bios.

I flashed my 4870 with my modded asus top bios and after flashing in atiflash the vendor id and bios version info is blank, i reflashed to previous bios before rebooting to avoid a brick...
Is this normal for a rbe modded bios?

just flashed my SAPPHIRE HD 4870 bios using atiwinflash, and using Asus 4870 top bios (128k version) said it completed, i rebooted and i get a black screen, no picture at all.

tried to recover using the advice on http://www.techpowerup.com/articles/overclocking/vidcard/152

left the 4870 in the pci-e slot, and used a pci slot card to boot. i can boot from the pci card( old geforce FX 5500), being in dos and using the command "atiwinflash -i" to see the number of my adapter didnt do anything. any suggestions?

[nafets]

You need to use ATIFlash 3.60 in DOS, as ATIWinflash 2.0.1.2 is a Windows-only application...

[Gendu]

do i need to actually create a bootdisk and go into dos that way? or is using the dos command prompt from start/accessories not good enough?

Step 1: create a new folder in the root directory of your C drive (so you can easily navigate to it in DOS).

Step 2: copy all the ATI WinFlash files and the new BIOS to this new folder.

Step 3: open command prompt and navigate to your new folder.

Step 4: use the normal ATIFlash command: "atiwinflash -f -p 0 [insert bios name here].rom"

it should take a minute or two to flash. it will tell you to reboot. you'll have to reinstall your video driver. but everything worked for me after that.

WARNING: if you don't get a successful confirmation at the end of the flash, make sure you flash it again before you reboot. you will brick your card if you reboot before a successful flash.

An excellent bios is attached to my signature.

when im booting from my pci card and not my pci-e hd 4870 which is a brick at this point, when i go into command prompt and type in "atiwinflash -f -p 0 4870.rom" (everything is in the right directories, im positive.) it doesnt do anything.

not sure what to do now.

[Fastmix]

Since you are booting with a pci, that one probably becomes 0 and the 4870 1.

Try typing "atiwinflash -i" see if it gives you a list of devices id.

[Fastmix]

Now if the 4870 is 1 type "atiwinflash -p 1 4870.bin/rom

[Gendu]

"atiwinflash -i" doesnt give a list of devices, it doesnt do anything for me. when i boot up it says one of my display adapters has been disabled because drivers do not match up. is there some way that i am supposed to re-enable the adapter?

this is what device manager shows for the card now.

[nafets]

Try booting into DOS and using ATIFlash...

[Fastmix]

So your card device id is 0, so try from dos atiflash -p 0 4870.bin

I don't understand, do you have a flashing problem...or a crossfire?

[BAGZZlash]

For god's sake, please read the tutorial (http://www.techpowerup.com/articles/overclocking/vidcard/154), it explains the whole flashing process in detail. :)
