HD4850 FireGL/FirePro counterpart?

[1c001guy]

Is it possible to hack either physicaly or with drivers to get the workstation benifits using a HD4850?

I believe the answer is yes, but not yet. I've been looking for answers to this for some time. The 3850/3870 can be done by hacking the drivers, but the 4850 still eludes people I think.

simply adding the device id's (VEN_1002%DEV_9442 from Catalyst drivers) to the FirePro_8.543 drivers doesn't work?

[hotpurple]

I don't think so, I believe it is more complex than that, although I have been wrong before. Could you lead me through how to do that please and I'll test it out.

I'd try editing the .inf file in the FirePro drivers (CH_71430.inf ?) and adding the device ID to use the V8700 settings;

"ATI Radeon HD 4800 Series " = ati2mtag_R7XGL, PCI\VEN_1002&DEV_9442

I found my 4850's device id (dev_9442) by searching through the CH_72276.inf from the Catalyst 8.12 drivers and copying the whole line, then adding the GL part to point it to the right drivers.

Insert it in to CH_71430.inf file as the last line in the device identifier section, like this:

"ATI FirePro V3700 (FireGL)" = ati2mtag_RV620GL, PCI\VEN_1002&DEV_95CC
"ATI FirePro V3750 (FireGL)" = ati2mtag_R7XGL, PCI\VEN_1002&DEV_949F
"ATI FirePro V5700 (FireGL)" = ati2mtag_R7XGL, PCI\VEN_1002&DEV_949E
"ATI FirePro V7750 (FireGL)" = ati2mtag_R7XGL, PCI\VEN_1002&DEV_949C
"ATI FirePro V8700 (FireGL)" = ati2mtag_R7XGL, PCI\VEN_1002&DEV_9456
[B]"ATI Radeon HD 4800 Series " = ati2mtag_R7XGL, PCI\VEN_1002&DEV_9442
[/B];
; General installation section

To extract the drivers just run the driver executable, then stop before setup runs and get into the extraction directory (likely and AMD folder on the root of your windows drive).

OK, I tried that. The drivers installed, but the workstation features did not function afterwards, i.e. the card functions as a standard hd4850 not a firepro V7770.

what workstation features?

You could always try changing the device id, using rivatuner (google the different 94xx device ID's and see which one matches a 4850, or use the 7750 device id)
