ami legal bios, supports p&p acpi 1.1, supports jumpfree, smbios 2,3,1 support, cppu, vccm, nb voltage multi adjuster. Its an fx8370 cpu on Asrock98ode3/u3s3 r2.0 mb. its new will only be running win 10 pro full install from DVD there won't be a second os on the machine at this time if there were to be it would be win7 but I can't see a purpose for win 7 at this time and it will be 64bit I will have 5hdd's permanently in the puter. My Hdd are mostly 750gb and I will be using the 750gb as one partition. I've got plenty of drive space so no point being frugal. I just though the two NTFS file systems would be the same. so if all the other drives were xp ntfs and the OS drive is formatted with win 10 that would be ok would it, would it?
