Tina, I believe the key here is that your BIOS is dated 1995.
Your best bet may be a 3rd party custom BIOS. At $69, I suspect that you can perform a major upgrade for just a little more money.
You didn't say what your system is, but in 1995, I suspect at best it is a Pentium Pro 200MHz.
At worst, it is a Socket 5 or a 486.
Either way, a newer system will take care of all your problems. For $200-$300, you can jump ahead 4-5 generations.
If you want to try the BIOS upgrade, you first need to identify who made your motherboard.
From www.wimsbios.com it looks like you have an aopen board.
2A5ICABA-00: Aopen (model: ???)
You can go to www.aopen.com and identify your exact motherboard, and see if they have a bios update.
Another option that would give you some of the benefit of a new motherboard would be to add in an IDE card such as the Promise Ultra ATA100.
This would give you ATA100 drive speed, and support for larger hard drives.
