I downgraded an Asus F7sr laptop from Vista home premium to XP home.
As mentioned in a prior post, I had some problems installing XP (until I upgraded the BIOS, so that I could run the hard drive in ATA mode).
Installing the device drivers was more difficult than I had hoped.
I use microsoft updates to install a few drivers (but not many).
Looking at the Asus website, I find NO XP drivers (I suppose I shouldn’t be surprised, the F7sr never had XP as an OS option).
I use the universal drivers from driverpacks.net, and I manage to install about 4 drivers (that leaves 5 unknown drivers).
Next, I use the Vista drivers CD that came with the laptop.
Wow, some driver folders actually contain drivers for both Vista and XP (even though the CD has “Vista drivers only” printed on it!).
OK, that takes care of a few more drivers.
I’m eventually left with unknown drivers for sound and dialup modem.
I download the modem driver from a similar Asus laptop (which does have an XP option).
And I finally get the sound driver working by searching the Vista driver CD, and running the setup program (which warns me about vista drivers not working on XP… but they end up working anyway!)
