Hello Ray,
The hardware that you would need is something called a BIOS programmer. Usually they use a USB port and might be found cheaply online. Flashrom has a list of supported programmers:

My suggestion would be to purchase a Raspberry Pi, which is a cheap Linux computer that has builtin hardware support needed to flash ROMs. It might be less trouble and more easier to get. The Pi, microSD card, case, breadboard jumper cables and breadboard (for easier seating of BIOS chip) may cost around $50 USD.
The Raspberry Pi certainly makes a nice, fast flasher, however the IO pins are connected to 3.3V rails so you'll need to be careful to use it with 3.3V flash chips only (not 1.8V).
I didn't know that there are chips that use 1.8 volts, I don't know much about electric devices, but could you just connect a resistor or something to reduce the voltage?
