Yesterday evening I posted a detailed tutorial that explains how to flash/update the IPMI firmware on the X9DRW-iF server from Supermicro. Today I’m going to explain how to flash the BIOS on the same hardware. If you’re not familiar with what a BIOS firmware flash is, there’s no shame in not knowing, here is a good explanation. I’ve found the documentation out on the web to be scattered at best, and a little bit confusing. This is why I thought I’d put together a start-to-finish guide here, where we’ll create our own custom bootable ISO, and use it to update to a specific BIOS firmware for the X9DRW-iF.
