Diddlesom Posted August 22, 2014 Share Posted August 22, 2014 Dell XPS 720 10.9 install,is this possible ? I have been searching around and seen people installing Snow Leopard but nothing later i can find is there a simple reason for this ? I have installed on Q6600 systems before but i cant seem to get to the install screen on this machine. I see no option to set the SATA to ACHI mode so i have just left it on RAID,im thinking this may have something to do with it ? Any help regarding this issue would be great,i jusy cant see why it does not like the install. Thanks in advance Link to comment Share on other sites More sharing options...
infinity5750 Posted August 22, 2014 Share Posted August 22, 2014 I succeeded XPS720 with Mountain lion 10.8.5 before.XPS720 chipset is not made from Intel. Install method is little changed from others.You have to put a lot of kexts for S/L/E after installed... Set a SATA = IDE in the bios, Make a MBR installer *Maybe possible to install for GPT (?)Patched IOATAFamily.kext for E/E USB stick. Or SATA3 card to set a AHCI automatically as very easy, see my thread. Sorry for I couldn't try now and am sold XPS720 is too big for my house. Go 4 it!

Administrators Hervé Posted August 22, 2014 Administrators Share Posted August 22, 2014 @Diddlesom: please post the detailed hardware specs, otherwise people who have no experience on this particular machine won't even be able to help you.

Diddlesom Posted August 22, 2014 Author Share Posted August 22, 2014 Thanks infinity5750 Im going to give it a shot,i built a myhack 10.9 usb and booted with the flags: -v -x GraphicsEnabler=No and it ran right through to the install screen but monitor went blank and says 'No Input Signal' after around 5 minutes the PC shut down. Hardware specs are: GTX460 card 4GB DDR2 Q6600 CPU Unsure of the motherboard think its a Dell YU822 Link to comment Share on other sites More sharing options...
Diddlesom Posted August 22, 2014 Author Share Posted August 22, 2014 the only SATA options in the BIOS are: SATA On Off or RAID I did a BIOS update too to A06 Link to comment Share on other sites More sharing options...
infinity5750 Posted August 22, 2014 Share Posted August 22, 2014 Try to add these combinations for boot flags listed bellow: PCIrootUID=1 or PCIrootUID=1 npci=0x2000 or PCIrootUID=1 npci=0x3000 or npci=0x2000 or npci=0x3000 Elementary sets are, PCIrootUID=0 npci=0x1000 I think.

Diddlesom Posted August 22, 2014 Author Share Posted August 22, 2014 Each of those flags result in the same 'no input signal' on the monitor think i will have to give up on this one or go back to an older os Link to comment Share on other sites More sharing options...
Administrators Hervé Posted August 22, 2014 Administrators Share Posted August 22, 2014 I'm not too surprised this XPS 720 is problematic: it's based on nVidia nForce 680i chipset, not an Intel one. So, you're probably going to need specific kexts to handle that. You probably won't be able to boot successfully with standard IOATAFamily kext.

infinity5750 Posted August 23, 2014 Share Posted August 23, 2014 I've been forget how to install it, But I think I tried out install with Mavericks. I installed Mountain Lion 10.8.5. I'm really forget a details...Sorry for that. I remember I saw Administrator Herve's 1st link is very helpful and you can do that. I experienced nForce 680i and 650i. *I look over them, They recommended Asmedia chip like me ! I thought I didn't over clocking with it, But I putted XEON X5365 work. It seem to be useless, attached the pix.1st one is the Core 2 duo E6700, Second is XEON X5365. Work with XPS720. Try it your next steps. Link to comment Share on other sites More sharing options...
