Radeon 8500 Mac/PC in Dual 867 help...

in Genius Bar edited January 2014
Hello... I'm generally fairly knowledgeable about Macs but before going out and spending some cash, I was wondering if anyone knew how to go about flashing the ROM on a Radeon 8500 video card... I bought a dual 867 g4 with nvidia geforce 4mx, but I want to go dual monitors, and have svideo out for dvd's.... thus, i need a radeon 8500 or 9700.... 8500 has similar performance and twice the ram so its better for dual monitor...

the pc version costs about ~$85 while the mac version is ~$185... i had heard whispers about the hardware being identical, i mean its just an AGP slot... right? so can i just buy a pc card? flash it? etc?

any help would be great!!!

    try checking over at <a href="http://www.xlr8yourmac.com,"; target="_blank">www.xlr8yourmac.com,</a> or look around on google. i know a few members here have done it, i think it saved them about $40. not sure if it's worth it in your case, on the off chance you fry the card.

    i'd tell you to search around, but i think the search function is broken now. it's gonna be fixed soon hopefully.

    best of luck!

    Here are the steps I used (gleaned from MacNN & xlr8yourmac forums):

    1. Bought PC 8500 Radeon card from Newegg.com rated at 275/275 for $109.

    2. Booted into OS9.2

    3. Installed Firmware RESTORE (from ATI firmware downloaded)into startup folder.

    4. Shut down. Removed original ATI card, installed Radeon 8500.

    5. Restarted leaving CRT unconnected, waited 5 min, shut down.

    6. Replaced Radeon with original card. Restarted, replaced the FIRMWARE RESTORE with Firmware UPDATE. Shut down.

    7. Reinstalled the Radeon 8500. Restarted. Waited 5 min. Shut down.

    8. Reconnected the CRT. Restarted and reset the PRAM (Waited for 5-6 chimes ... lost count{sheepish grin})

    9. Installed the drivers in OS9. Booted into OSX Installed he drivers and everything is working great.

    Good luck with your upgrade, Michael. Sorry I can't help you with it, but when you get your new card, I'll give you $40.00 for the geforce 4mx.
