I have successfully loaded the ATI Mobility Radeon 7500
Driver from the SP27665 (an HP/Compaq
driver file). I have a Compaq EVO N800c. The install does not work, however it will extract the files to: C:\swsetup\SP27665\
Driver\2KXP_INF. Then under Device Manager choose to Update Driver (under the Generic VGA) , select Brows My Computer; choose Let Me Pick, say Have Disk and browse to the above folder ( C:\swsetup\SP27665\Driver\2KXP_INF). 2 options appeared for me, I chose the first, my system start dinging and flashing a few times (around 10) and then all was normal. I did not say to reboot, but I tested Freecell and it said there was no hardware acceleration still, so then I did a reboot and presto! no more message about Hardware acceleration being disabled and the cards fanned out in there fancy way. I've only done this about 5 minutes ago, so I don't know how things will function long term, although I've also only been running 7 for about an hour... Hope this helps.
