As far as the voltages go, I'm not sure I understand unman's "garbage" comment. The PROMs on your X-230 are 3.3V logic, but the CH341A programmer usually has 5V logic. I've heard that some CH341A are 3.3V, but that seems more because there are several different places in China producing the same board and so its kind of random.
I think you can use 5V logic to program these ICs, but you are doing so at your own risk. There is no current limiting resistor on the CH341A board, and some of the CH341A ICs have no label, which indicates a potential "back ally" fab (i.e. counterfeit) that is common with low end Chinese electronics. Point is, you'd be driving you motherboard with a potentially out of spec, using an unknown IC at the wrong voltage, without current protection. This is not necessarily safe for your Mobo, but it *might* work for you. There is a mod to turn your programmer into a 3.3V device, but it seems the mod doesn't work on newer programmers that don't have labels on the chip. It didn't work for me, and internets reports that it didn't work for others. I used a Raspberry Pi instead : https://tomvanveen.eu/flashing-bios-chip-raspberry-pi/ The trick for the RaPi was the arg "spispeed=512". I connected the Pamona clip included in the CH341A Kit to the RaPi using fly wires, so my CH341A wasn't completely useless, and was actually cheaper than the clip alone.
