Hello, I have just come across a similar problem.
I am building a new PC, based upon a KV7 motherboard and a 160GB SATA harddrive.
I had not appreciated that the drive would not simply be a straightforward boot up device.
I have tried a number of the suggestions made earlier in this thread, but am stuck with either the DMI pool message, or if trying to install WinXP, a message of "textsetup.oem caused an unexpected error (512) at line 1742 in d:\xpclient\base\boot\setup\oemdisk.c" the message is followed by the inevitable "press any key". This is with an internal DVD and floppy drive installed.
Strangely, putting in a conventional IDE harddrive, with a working WinXP installation from another PC, instead, doesn't seem to help.
Is it me?. I have built a number of PCs from scratch, and never been as stumped now.
Anyone's help would be much appreciated.
By the way, I'm new on the forum, but it looks great.
