Sorry I may have been wrong before. It looks like you may be able to use a 160GB PATA hard disk with your motherboard.
I did some googling and I found this info regarding hard disk sizes and mobo BIOS:

Since nowadays LBA mode is used, you could think that there is no more limitation in hardware for the maximum hard disk drive capacity. However, ATA interface uses a 28-bit variable to address sectors under LBA mode, creating a 128 GB (or 137 GB if you use the wrong definition of gigabyte) limit (2^28 x 512 bytes).
ATA-6 standard (a.k.a. ATA/100) increased the size of the LBA variable to 48 bits, pushing the size limit up to 128 PB (petabytes, one petabyte is 2^50, so 128 PB is equal to 131,072 TB) a limit that seems impossible to reach (let’s see 10 years from now if this statement continues to be true). By the way, this limit is also known as 144 PB limit, if the wrong definition of petabyte is used.
So according to the above you need ata-6 support in your mobo. Now can you confirm that your mobo is the Intel® Desktop Board D815EEA (You have written slightly different model number)? If that is correct then I found this page on intel's site:
According to the specs on intel's site your mobo does support ata 100(ata-6). So it looks like you may be able to use a 160GB PATA hard disk with your motherboard
