hi.. i just downgraded my sony vaio vgn-c25g from vista to xp.. but i could
not get xp sound card (PCI) driver.. need help..

Just finished reinstalling XP on a Vaio for a friend. NEVER again.
After formatting with a generic XP disk(home,pro or media center) it
wouldn't accept the license pasted on the back. Luckily was able to get
it booted, and let Sony's website tell me exactly which Vaio disk to order.
Long story short, very proprietary. Let Sony's website autodetect exact
model, spend the 20 bucks for reinstall disk. Hopefully there will be
one for XP for it.
Good luck.
