BIOS sees only One drive at a time

The Original problem - the desktop PC continuously restarts when attempting to boot. The logo screen comes up, there is a single beep, then the computer restarts. This happens over and over; the time the logo screen stays up varies, sometimes the restart is immediate, other times as long as 15 seconds. I have been told it would eventually boot into Windows 7 Ultimate (32-bit), eventually - I have not seen it do this myself.
After doing the normal things - reseating the RAM, clearing the BIOS (setting to Optimum Defaults), checking PS, etc., there is no difference. Attempting to enter Setup, it has the same restart problem. It does act like it gets better the more it warms up.
The m-board is a Biostar P4M900-M4 ver 6.1 with an Award BIOS v6.00PG with the P490M117.BS update (the only one available). The HDD is cabled to SATA1, one of the CD-ROMs to SATA2, the other CD-ROM to IED Primary, the Floppy drive to the FDD header.
In the "Standard CMOS", only the CD-ROM on SATA2 is listed. If I "unhook" the ROM, then the HDD is listed on SATA1, but it is the Only drive listed! It is also displayed on the Splash screen (?) this way, along withe the FDD as "Failed".
Other than reinstalling the Chipset drivers, I have no idea where to even start to fix this problem, I simply do not understand the how, or why what would cause this. But I guess that's why I'm here asking for your help .
I will appreciate any help you can give me - TIA.
