Hello sir. I have read the entire thread.

Whooo. Glad that is over.
Now, there are a few issues that are at play here, and it appears you have already discovered a couple of them.
I'll try to throw some suggestions out here. I'll need you to be specific (as you already have been) as to what messages or results you get. Your motherboard is VERY limited on SATA/RAID settings, and further reading appears to suggest this motherboard has trouble with SATA all together. So, I do not know wha to expect here. It appears your motherboard will not support 3GB/s SATA modes. Only 1.5GB/s is supported so the hard drive has to be set to a slower speed to work. This is easily done on your Seagate drive with a jumper, so lets work with that drive.
Here are some of the issues that have been present throughout this thread. First of all, when you plug a hard drive into this machine that has been setup on a different machine, you MIGHT get lucky and have the drive boot, but USUALLY you WILL NOT get it to boot. The operating system has been custom taylored during installation time for the hardware on the machine it was installed on. Any significant change in hardware (such as plugging the hard drive into a different computer) will prevent Windows XP from being able to start. Therefore, plugging a drive that you know to work on a different machine, into this machine, is not a reliable test. It cannot, and should not be done.
Next, as you have discovered, and as Digerati has pointed out, Windows XP can not see a SATA hard drive without loading SATA/RAID drivers using the F6 button and a floppy drive during the initial stages of setup. There is no other way to do it, that I know of, without a floppy drive. There are no clear options in your BIOS to work around this but we will try the only one I see in a minute. Its almost looking like you will have no choice but to plug a floppy drive in temporarily and load the correct SATA drivers. But, we'll tackle that when the time comes.
Also, the message about the bios not be installed, or whatever, is your SATA controller not detecting the SATA drive properly. This appears to be multiple possibilities, either bad SATA cable, bad power cable, or most likely no 3.0GB/s support. It is not referring to your motherboard BIOS.
Lastly, you mentioned at one point that you tried several different hard drives, and with two of them the machine wouldn't even turn on. This is highly unlikely to be anything related to the drive, especially when the seagate drive worked previously. Therefore, the answer to this problem is simply this - you bumped some cables around and caused furhter issues. So please make sure everything is plugged in securely after you make changes like that.
Now, lets get down to resolving this issue. Here's the steps.
Inspect your Seagate hard drive. It will have a jumper setting labeled on the case to limit it to 1.5GB/s mode. You will need to put this jumper in place.
Next, disconnect the fujitsu hard drive and connect the Seagate harrd drive. Please plug it in, both SATA and POWER cables, and power the system up. The system should power up just fine. If it doesn't, please re-check your connections, but I doubt you will have this problem again.
Power the system up and enter your BIOS setup screen.
Configure your bios as so:
First, navigate to the EXIT menu and choose "Load Setup Defaults"
Next, navigate to the ADVANCED menu, navigate to the I/O Device Configuration option/menu, and change the option Onboard ATA Boot ROM to DISABLE.
Now, navigate to the EXIT menu, and choose to save your settings and exit. When the computer reboots enter back into the BIOS setup utility.
Under the MAIN menu, please tell me what is listed for Primary Master, through Secondary Slave drives. It appears your BIOS is so limited that it will not support SATA in the BIOS at all. Therefore, your SATA drives absolutely will not show up in this list.
Now, navigate to the BOOT menu and ENABLE the Atapi CD-rom and make it the first device in the list. Save your settings in the EXIT menu and reboot with your original Windows XP installation disc, lets not use the slipstreamed disc for now. Go through the setup process and see if it gives you a drive not found error again. If it does, go back into your BIOS setup, navigate back to the ADVANCED menu, navigate to the I/O devices menu, and ENABLE the ATA Boot Rom again. Save your changes and reboot. Make a note if you get a message about the "bios not be installed" again, and try the windows setup also and see if it will work. If it still gives you a hard drive not found error, then you have no choice but to find a floppy drive for now and create the floppy disc with the right SATA drivers.
Please post back with the results of what you find here, and we will go from here. Again, if you cannot get setup to recognize the hard drive you will need to find a working floppy drive and floppy disc for the time being and you will need to be able to create the floppy disc on a working windows machine so it can be used on this non-working machine.
