JMB363 SATA DRIVER

I did not experiment with the values of these bits except for toggling bit 6. I want to boot an ide hd from a jmb card. The problems with configuration register 0x are more problematic. They seem important, causing PCI config register bits 0xed[5: Duufus, I had in the past this card: I did have some issues with the card being seated properly in the PCIe slot. I think what you want is to change b1 02 to b1

You know if it is possible?. This changes mov cl, 0x02 to mov cl, 0x The option ROM loads, correctly reports connected drives, and allows booting from them.

The sum of all bytes in the file should be 0x Linux sets register 0x41 to 0xa1, while the option ROM will set it to 0xf1 or 0x Register Function 43 Defaults to 0x Therefore, I chose to mjb363 register df[6] to cause the option ROM to quit without detecting drives. Option ROM sets this to either 0xf1 or 0x Email will not be published required. I did have some issues with the card being seated properly in the PCIe slot.

As for me, I no longer have the card…. You can download 1. They certainly appear to be the same, I have replaced the orom inside the bios of the R3E and the device is now running in AHCI mode. I want to create an AHCI patched verson of 1.
