The bytes that were changed here are x86 code that reads the PCI configuration register and does something with the value. Hey Mac, thanks for the link to XS. The last byte of the file is used as a checksum. Therefore, I chose to set register df to cause the option ROM to quit without detecting drives. I used the newest version of the option ROM 1. So do check the UDMA status before doing any fast burns.

I want to use latest bios because it will be better 1. As for me, I no longer have the card…. In no case did setting 0xdf cause the JMB to become a multi-function device. They seem important, causing PCI config register bits 0xed[5: It works for a single drive, but doesn’t support port multiplying, which is what I need. You can use these HTML jmjcron.

Upon further investigation I found out that the value is combined with a mask which allows 0xXb, where X can be anything, so it would match 0xb anyway. The whole section currently looks like this:. I only found drivers… http: Why do you want to avoid the on-board SATA controller? I also used pcicfg in DOS to check the jmicrin was detected.
It seems like bits [1: If so, I would start with the first patched ROM the one that sets df[1: They all work fine. Skiprom works best for me in hackintosh. This was due to the JMicron-chip. Sorry, forgot to update CRC.
Posted February 4, I have read through this page and start to comprehend the edits needed. There is indeed a checksum byte. I did have some issues with the card being seated properly in the PCIe slot.

Yes that’s what pfix does. Therefore, I chose to set register df to cause the option ROM to quit without detecting drives.
The option ROM loads, correctly reports connected drives, and allows booting from them.
Header Type ‘non-bridge’ single-func Vendor: I did a burst-test on all my writers and I stick by my earlier conclusion:. Do i need to fix a checksum value as well?

Option ROM sets this to either 0xf1 or 0x Thus it seems like setting 0x41[7: You know if it is possible?. Unfortunately, I do not know enough about hex editing to find where to patch.
Sign in with Twitter. Trying to do that in the option ROM causes a several-minute hang during boot when loading the option ROM again, seemingly jmicroh for a disk and giving upeven when a PATA disk is present. Sign in Already have an account?
