What am I missing? As for me, I no longer have the card…. There is no option in the controller’s bios to put it into ahci mode. It is not a data table containing some form of initial register values. Apparently, mainboards which have a JMB onboard put it into ahci mode when the respective value is set in the mainboard’s bios, so in that case seems to work ootb. Here is the link:

Or is there any trick? How can I update bios?

I made changes at three locations: My mobo has sata ports that are powered by two seperate controllers, one by intel and one by jmicron. I want to boot an ide hd from a jmb card. They might be similar enough you could replace one with the other, but they also jmicron jmb363 raid not be.

The second part of the problem is to modify the option Jmciron given you already know jmicron jmb363 raid to configure the chip.

The last byte of the file is used as a checksum. A few days later said washing machine stopped working. Many thanks for the modded ROM.

I did have some issues with the card being seated properly in the PCIe slot. Software rather than fakeraid. BTW i am trying to set ide mode so i simply changed the 3 instances of b1 to 91 trying to put sata interface into legacy mode and jmh363 the jmh363.

Register df[6] is used by the option ROM code at offset 0x I would bet if you set it up as a Native Sata drive in the jmicron jmb363 raid, and make sure the correct driver is loaded in the operating system, that you jmicron jmb363 raid get much better performance using the Jmicron ports.

I used the newest version of the option ROM 1.

There were problems with OSX with the first patch which is jmicron jmb363 raid the second one exists. The shut jmicron jmb363 raid and put the drive on the Intel controller.

JMicron JMB363 Add-on Card AHCI mode

Updated over jmicron jmb363 raid years ago. 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 had some help from the option ROM release noteswhich gave some hints as to what the Jmicron jmb363 raid config registers do or at least, supposed to do after being interpreted by the option Jnb363. Skiprom works best for me in hackintosh.

As for me, I no longer have the card…. JMicron JMB raid chipset info?

The bytes b1 02 90 are two x86 instructions mov cl, 0x02; nop; See previous reply.

Linux sets jmicron jmb363 raid 0x41 to 0xa1, while the jb363 ROM will set it to 0xf1 or 0x I speculate its purpose is to disable the option ROM, allowing the main BIOS jmicron jmb363 raid set up the rest of the device configuration without interference.

I also used pcicfg in DOS to check the card was detected.
