JMICRON 363 DRIVER
Option ROM sets this to either 0xf1 or 0x I speculate its purpose is to disable the option ROM, allowing the main BIOS to set up the rest of the device configuration without interference. I tried modifying the option ROM to also configure register 0x to this value, but had many problems booting. They might be similar enough you could replace one with the other, but they also might not be. Trying to do that in the option ROM causes a several-minute hang during boot when loading the option ROM again, seemingly waiting for a disk and giving up , even when a PATA disk is present.

Register df is used by the option ROM code at offset 0x This is done the same way as with any other disk.

I have two HDD conect.
Why do you want to avoid the on-board SATA controller? Sorry, forgot to update CRC. This seems to put the controller in AHCI mode. I did have some issues with the card being seated properly in the PCIe slot.
This changes mov cl, 0x02 to mov cl, 0x It would be great if you can test it. Anyway, you can erase the flash chip, so that no option Umicron is executed and the card is rendered non-bootable anymore.

At this point in the code, register cl should contain the byte read from PCI configuration register 0xdf. The bytes b1 02 90 are two x86 instructions mov cl, 0x02; nop; See previous reply.
