A modified BIOS is available with AHCI

Is it worth it to install windows 7 64 bit

Can I install a new version of the ati driver for windows 7 32 bit

Please help me ,

I want to use in my laptop in SATA and not use IDE

windows 7 64bit on this laptop will be better for ssd

Does this laptop runs on SATA II (3Gbit / s) or only IDE
