Problems installing XP (SATA drive)

eheh.. typo on that vid card..
But ive called tech support..ran it over with em and so far it hasnt voided the warranty that they've said. But along with the backorder speakers they're sending the driver disk that should have been sent with the original system disks box. From all they've said the drivers are the exact same as the ones on the cd and on the download site.. but 3 refuse to copy.. ive opened the .sys that wont copy with ms word.. and clearly written is "this file cannot be copied from dos" correct me if im wrong.. but dosent XP setup use a form of dos? Only other info i can think of posting is the 3 files that refuse to be copied.
si3112r.sys
siwinacc.sys
