Except, don't use the BIOS to write the logs, but rather code/use a very simple set of polling-PIO functions to talk directly through the PIIX to the drive. Really really simple code to do that, and it would likely work with anything ata-piix, and most other non-AHCI chipsets too. Not perfect, but probably good enough for a lot of scenarios. The old hd.c driver shows how to read/write a sector at a time, and that kind of code is easily converted to simply poll for completion.
