Looking for a Gigabyte mobo

Am looking for a Gigabyte mobo ($80 or less)with these specs:
Athlon XP
Dual channel DDR
Socket A
400 FSB
8X AGP
These are what were found in searches:

And this:

Which mobo would work best?

Am upgrading from a GA-7IXE4 Gigabyte mobo.The BIOS of the old mobo had "boot sector virus protection", and "BIOS write protect". Do the new ones?
Do all the Gigabyte mobos have dual-BIOS?
