I just completed building a new computer using an ASUS A7N8X MB, a new Westerd Digital HD, a stock floppy drive and a CD reader/writer. The POST operation is successful with the HD, floppy and CD drives being recognized in the BIOS. Altough BIOS is set to boot from Floppy> CD> HD order, it immediatelty goes to boot from CD drive.
I'm able to boot from the CD drive using a MS Windows XP OEM Preinstallation Kit disk that provides a DOS prompt from D; however, if I type A:, it responds with "device not ready" or if I type C:, it responds with "no such drive" which means the HD and floppy drives cannot be accessed. The MS disk has many tools including the Format command which I would use to format the new HD but it cannot find the HD.
I also tried booting from a WIN XP Professional CD but it halts after the initial setup and cannot continue. The error messages does not provide details.
Since POST finds and recognizes both the floppy and HD, why can't I access them?
