jarobata Posted February 12, 2008 Share Posted February 12, 2008 I get kernel panic when my computer tries to use all my memory. I've read this is a common problem, is there no possible fix to allow all 4GB? Also could someone link me up to explicit instructions on the maxmem fix? I can never find anything on this forum.

radov4n Posted February 13, 2008 Share Posted February 13, 2008 I am not sure as I don't have DS3L. But some P35 ICH9 boards allow you to switch to AHCI mode, apparently it solves 4GB problem for some people. Also someone reported that it might be because of jMicron kext. If you don't use jMicron, you can delete it.

To be more specific an IDE device connected powered on using the jmicron controller will do it or that was so with my spare machine using the SATA jmicron works great never tried the IDE on my DS3L.

Enabling AHCI mode fixed the problem but now I can't boot into XP. is there any fix for this?

MacUser2525 Posted February 13, 2008 Share Posted February 13, 2008 Enabling AHCI mode fixed the problem but it says it's for vista only, can I not boot into xp with ACHI enabled? To use XP in AHCI mode you need to have installed with using the F6 option to load third party driver from floppy disk or you can try here to do it afterwards.

byusinger84 Posted February 13, 2008 Share Posted February 13, 2008 I agree with the previous poster. You need to install XP with AHCI already enabled. I have a DS3L board in another computer of mine. Works just fine with 4 gigs of ram. I have 8 gigs on this computer and it works fine too!

jarobata Posted February 13, 2008 Author Share Posted February 13, 2008 To use XP in AHCI mode you need to have installed with using the F6 option to load third party driver from floppy disk or you can try here to do it afterwards. I followed that guide and it wouldn't boot after. Does it matter that I downloaded the most recent driver? Also it calls for copying iastor.sys and I just found a file name iastor that was listed as a system file. I assume that was the correct file. Anyone have any input here? I followed link and downloaded the most recent file, copied iastor, updated the registry with the given file, and rebooted. Changed to AHCI and it wouldn't boot. Was I supposed to do something else? Was I supposed to use a different intel file or change that registry patch? Assuming I can't make it work this way, where can I find the driver to install if I have to reinstall XP? I'm pretty sure I need a driver to F6 install because it didn't even see any hard drives when I didn't do anything special. Does anyone know if when I do the reinstall if it'll screw up the darwin bootloader? I've always installed XP first and then OSX.

jarobata Posted February 14, 2008 Author Share Posted February 14, 2008 I could send you the working files.try too boot with the "last known working configuration" Will that nullify the changes I made to the registry? I'll def try your files assuming they're not viruses lol. Edit: I can no longer reboot or shutdown successfully. Is this an effect of AHCI?

socal swimmer Posted February 15, 2008 Share Posted February 15, 2008 Here is how to limit ram: sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple$ <plist version="1.0"> <dict> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>debug=0x100 maxmem=2048</string> <key>Timeout</key> <string>8</string> <key>device-properties</key> <string>2f0100000100000001000000230100000700000002010c00d041030a0100000$ </dict> </plist> btw, the debug thing gives you debug information on kernel panics. its useful. don't forget to save when you are done!

Maybe it is my IDE hard drive. Link to comment https://www.insanelymac.com/forum/topic/87207-4gb-possible-on-gigabyte-ds3l/#findComment-625754 Share on other sites More sharing options...

Maybe it is my IDE hard drive. If I have AHCI mode I can run OSX but not windows. I am running all SATA drives. I just need to get windows working with it and I'll be all set. I'd straight up do a fresh install but I don't know where to get the proper AHCI driver for F6 installation Link to comment https://www.insanelymac.com/forum/topic/87207-4gb-possible-on-gigabyte-ds3l/#findComment-625814 Share on other sites More sharing options...

rimmi2002 Posted May 22, 2008 Share Posted May 22, 2008 I am going to re-install my XP and want it to work with AHCI. However, I don't have a floppy drive. Is there a way I can install the AHCI drivers from a USB or a burned CD at this part in the installation menu, or does it have to be floppy?

Schweppes Posted May 22, 2008 Share Posted May 22, 2008 I installed Leopard 10.5.2 on this mother (DS3L) with 2 SATA 2 HDs and 1 SATA DVD drive, if i enable ACHI in bios only 2 SATA ports work. I dont like to use maxmem, i have 4 GB of ram and i like to use 4 gigas. If i dont use any IDE devices can i disable IDE in bios and delete JMicron.kext to solve the kernel panics?
