To make the long story short, I need to make my new 486 build recognizing HDDs larger than 540MB, and I decided to give XT-IDE ROM / NIC combination a go.
I have an eprom programmer and necessary software, though I'm quite new about the whole subject.
I read around a lot about what to do and how to do it, and gain same information too, but it is not complete and sometime even contradictory. I need more like an "idiots guide to flasing XT IDE BIOS for 3com NICs" 😊
I decided to use the ROM image compiled for At/386 machines and the one with a boot menu. This means I need at least a 16KB EPROM but I really want to do it with an EEPROM
So the questions are:
- What kind of EEPROM should I use with the 3com 3C509B COMBO NIC that I have (I have no problem about using its configuration software, setting up ROM adresses, etc.) or should I stick to the EPROMs? I have CAT28C256P-20 EEPROMs and NMC27CP128Q EPROMs
- What is this "adjusting the parity bit" thing that people are mentioning about to succesfully flashing the ROM?
- Should I really burn multiple copies of the image to the EPROM/EEPROM till to fill it?
- What else should I take into consideration?
Please note that this will be my first use of that eprom programmer, so don't hesitate to tell me about it like you would tell it to an idiot 😊
