|Did you buy this laptop brand new with Linux installed. BTW, I don't know what Linux DOS is.|
Surprisingly, the Acer site has WinXP drivers listed.
WinXP doesn't include native support for SATA hard drives. So, either the BIOS configures the SATA drive to run in an IDE compatibility mode, or the vendor included the chipset drivers when installing WinXP.
Did you get the CD that you are trying to install WinXP from that vendor to use as a restore disk?
Below is a link to all the drivers for that laptop.
Explain why you were re-installing WinXP in the first place.
