I found a motherboard (an ECS P6BX-A+) and it has a BIOS update to support >40GB hard drives. However, the update is only supported on 2MB BIOS ROMs; this same board can have either 1MB or 2MB. Could I simply pop in a different size ROM if I get a 1MB board? If so, what exact chip do I buy?

The one I linked to in the thread should also work in your motherboard, but check the data sheet to be sure. What EPROM chip is a 256K compatible replacement for the 128K Intel P28F001-BXT-120?

Could something like this work assuming it has the correct pinout?

Admittedly I'm not too sure about these sorts of things, so I could be totally wrong

Don't use EPROM, its programming works totally different.
The first one (EEPROM) should work. But you can also take any used 2Mbit chip for this which you salvaged from a dead/useless mobo.
