JMicron IDE DVD drive 'com.apple.Boot.plist not found' error fix

This issue should have been fixed ages ago, but at last we've done it. How? It was really easy. For some reason nobody was brave enough to trace down what's going on when booting the Darwin loader using an IDE DVD attached to a JMicron controller in IDE mode.

 

I had the suspect that JMicron controller is just fine but its int 13h option ROM implementation reports different drive characteristics as it supposed to be. Actually Darwin uses EBIOS calls to gather the drive information and it should also report the cylinder, head, sector (CHS) parameters. Unfortunately in case of using JMicron it just doesn't happen. This is the first step where things getting worse.

 

… and getting even worse: Without the above parameters, Darwin loader uses an ancient BIOS call to query the CHS values. This is the second – and fatal – step to prevent the loader working properly. In case of JMicron this call will return with an error and the story ends.

 

What could be the solution then? Since only LBA addressing is being used to read sectors from HDD or DVD there's no need to worry about the CHS addressing support. It means we can safely remove the above check for the CHS parameters and also the alternative gathering method ;-)

 

If you want to try it out here is a zipped boot image ready to download. After extraction burn it with Disk Utility.

 

How to apply PPF file?

 

Use a program like ppf-omatic [google it]

 

[Please sticky this!, I've been looking for a fix for ages, and I'm sure others have been too!]

If this works, you are a GOD!

 

I can confirm it works for me:

 

ASUS P5B Deluxe WiFi

4GB RAM

2.4 GHz Intel Core 2 Duo

Sound Audigy Card

ATI Radeon X1900XT 512MB

320GB HDD

JMicron/IDE/LG DVD Burner

 

Will report once I install it!

 

Also please, all developers include this in the next Mac OS X Update if you can! It would make a world a difference for many!

Im burning the DVD right now. Did you write this or did you find it? Well done in any case :thumbsdown_anim: Ok well its certainly helping my install, it gets through about 2-3 pages of code now before any errors. Would anybody be able to help me figure out whats causing these please. I believe the FIX DOES indeed work and this is something else but all the same :D I dont have a mac to edit from and im using Kalyway_10.5.2_DVD_Intel_Amd Just so its clear, these are pages ~3 4 5 of code that comes up. It all looks good up until these.

I found it, but I wasn't able to post the link, for some reason it won't let me.

 

& It should work with any processor which supports at least SSE2 or greater
