Please continue sharing your ordeal as I am exeriencing the same symptoms.
I had the p5b plus MB oprating with no problems in a separate case with ide hd and dvd player on same ribbon using cable select.
With new case I am using a WD Sata HD and IDE DVD and floppy. All devices are detected but i have not been able to get the floppy or dvd to boot yet.
Will report more later....
I pulled the lite-on DVD and slapped in another and it booted just fine. Not sure what is wrong with the new one.
I have noticed with this p5B Plus board, if I try to boot with a windows XP with SP2 already included, I get a blue screen of death. If I use an older XP Pro CD not yet updated for SP2, It will install XP just fine.
I am afraid I will hit the wall of blue screen death again when I update with SP2 - like happened last week with a different case, causing a complete reinstall.
Anyone else have experience with this? Thx.
