Does Jmicron E-Sata on GA-EP35-DS4 work?

[GerdJ]

Hi there,

 

I'm using 10.5.7 on my Gigabyte GA-EP35-DS4 Rev. 2.1 with disabled Jmicron Controller. I have 2 internal SATA HDD's and one SATA DVD drive connected to ICH9R controller AHCI. All ok!

 

Yesterday I bought an external E-SATAII HDD-Case from Fantec (LD-H35US2) and connected it via E-SATA slot bracket to the ICH9R controller. This gives me problems like, bad performance, systems seems to 'wait' for 20 sec. every time I want to access the external HDD, sometimes the external HDD is not seen at all, USB works!

 

I want to know, if the other SATA controller onboard (Jmicron) is supportet by 10.5.7 and if it is AHCI compatible in OSX (hotplug an so on), are there special kext i have to load? I know there is a PATA kext for the controller, is that all I need?

 

Thank you very much :-))

Hello, I'm just googling now for a solution to have eSATA ejected: so far I rethrieved some information on having the bracket plugged to the purple JMicron SATA ports w/ AHCI enabled in BIOS. I'll report later if this works adding JMicronATAInjector.kext to .mkext and will link references. This post is useful to me as notepadding. Now I'm backupping my HDDs and it will take long. I must be careful because I had the newly bought 1Tb HDD replaced today after the summer vacation as it probably failed and broke off because of hot ejecting while in OS X (yet unmounted before from Disk Utility. I did not try unmounting by Terminal).

Gigabyte's JMicron363 SATA2 device and vendor IDs are 0x2363197b (at least on my EP35-DS4 Rev. 2.1)

JMicronATAInjector.kext is used to add ATA support, not SATA as needed in present situation.

Possible considered solutions:

 

AHCIPortInjector.kext (legacy from Chameleon-2.0-RC2-r640) has to be edited removing the IOKitPersonalities' JMicronAHCI child:

<key>JMicronAHCI</key>
	<dict>
		<key>CFBundleIdentifier</key>
		<string>com.apple.driver.AppleAHCIPort</string>
		<key>Chipset Name</key>
		<string>JMB36x AHCI</string>
		<key>IOClass</key>
		<string>AppleAHCI</string>
		<key>IOPCIPrimaryMatch</key>
		<string>0x2360197b&0xfff0ffff</string>
		<key>IOProbeScore</key>
		<integer>2000</integer>
		<key>IOProviderClass</key>
		<string>IOPCIDevice</string>
		<key>Vendor Name</key>
		<string>JMicron</string>
	</dict>

So Gigabyte's JMicron SATA2 controller is recognized (IODeviceTree:/PEX4@1C,4/JMB0@0 in EP35-DS4) and managed by retail 10.5.8 AppleAHCIPort.kext in S/L/E as Unknown AHCI Standard Controller in System Profiler.

I suppose this is the IOKitPersonalities' GenericAHCI child involved:

<key>GenericAHCI</key>
	<dict>
		<key>CFBundeIdentifier</key>
		<string>com.apple.driver.AppleAHCIPort</string>
		<key>Chipset Name</key>
		<string>AHCI Standard Controller</string>
		<key>IOClass</key>
		<string>AppleAHCI</string>
		<key>IOPCIClassMatch</key>
		<string>0x01060100&0xffffff00</string>
		<key>IOProbeScore</key>
		<integer>800</integer>
		<key>IOProviderClass</key>
		<string>IOPCIDevice</string>
		<key>Vendor Name</key>
		<string>Unknown</string>
	</dict>

Otherwise AHCIPortInjector.kext can be deleted. A suitable DSDT.aml can be compiled to solve the Unknown AHCI Standard Controller being recognised as ICH10R in System Profiler or whatever ICHx fits to your hackintosh.

 

Now I'll test adding

<key>JMicronAHCI</key>
	<dict>
		<key>CFBundleIdentifier</key>
		<string>com.apple.driver.AppleAHCIPort</string>
		<key>Chipset Name</key>
		<string>JMB36x AHCI</string>
		<key>IOClass</key>
		<string>AppleAHCI</string>
		<key>IOPCIClassMatch</key>
		<string>0x01060100&0xffffff00</string>
		<key>IOPCIPrimaryMatch</key>
		<string>0x2368197b 0x2363197b 0x2361197b 0x2360197b</string>
		<key>IOProbeScore</key>
		<integer>2000</integer>
		<key>IOProviderClass</key>
		<string>IOPCIDevice</string>
		[b]<key>Protocol Characteristics</key>
		<dict>
			<key>Physical Interconnect</key>
			<string>ESATA</string>
			<key>Physical Interconnect Location</key>
			<string>External</string>
		</dict>[/b]
		<key>Vendor Name</key>
		<string>JMicron</string>
	</dict>

to AHCIPortInjector.kext, the bold strings used to have them ports recognised as eSATA.

I do not know if I'll keep the bold part. They should already be eSATA capable because of AHCI.

USB drives have indeed false Ejectable key value in IORegistryExplorer. I read correcting this report is merely cosmetic.

I do not want to mess up S/L/E so, to keep vanilla, I'll try to create a legacy .plist kext to put in E/E

Hello,

 

so what is the bottom line with the Chameleon AHCI-Injectors?

 

I am soooo sad that I have lost my old hot-swap-ability... which used to work PERFECT in old 10.5.3

 

Does anybody have a solution for this with 10.5.8 and using the EFI-boot partition with Chameleon 2RC?

 

Anyone try Dune's KEXT and delete the Chameleon injectors?

 

hiside,

ninetto

I too would like a solution here.
