I'm working on a 2007 20" iMac trying to get Windows 2000 running well. I believe it has a Mobility Radeon HD 2400xt.
I was unable to install the drivers provided from apple for windows XP through device manager, even though the right hardware id was present.
"ATI Mobility Radeon HD 2400 XT" = ati2mtag_M72, PCI\VEN_1002&DEV_94C8&SUBSYS_0084106B
The installer also didn't work, when I tried it with SP4 + UR1. I would try BWC's drivers, but they also don't appear to support this device.
Does anyone have any idea on what the right direction to go from here is? Thanks.
