Should work. But..... I have a really bad experience with OEM formatting utilities - sometimes they write something in the boot sector not accessible by DOS. Thus, repartitioning and reformating using DOS is nearly impossible - OS keep on calling for the OEM Utility. Ultimatelly I had to use Norton Disk Doctor (ol' DOS version!) and manually clean up the disk - that was pain. Since learning that, I NEVER use OEM disks to format the HD.
