This is probably an Intel problem but since Intel no longer supports my MoBo, here goes.
Intel 82801GH I/O Controller Hub (ICH7DH) SATA Controller in IDE mode. Windows 7, SP1, Home Premium, 32 bit. Plextor DVDR PX-L890A ATA Device. HD and CD-ROM both connected to black connectors on Intel D975XBX2 MoBo. BIOS set on default. With CD-ROM connected POST proceeds normally until it gets to "EB" test where it hangs for 2 minutes then proceeds to integrate with the OS. When integration complete, the CD-ROM and OS operate normally. If I disconnect the CD-ROM from the black connector, POST and integration proceed normally and rapidly. Any ideas/insights appreciated.
