PopeOnABomb Posted April 14, 2008 Share Posted April 14, 2008 I have four GX-270s. One of them is a 2.8ghz and the other three are 3ghz. They all have identical ram (2gig), harddrives, BIOS versions, video cards, and wireless cards. Identical down to which slot each PCI card is lcoated in. I installed OS-X 10.5.1 Kalyway on the 2.8ghz machine without any problems - it is a perfect installation. So I decided to install OS-X on the other machines. (there is no point, but this is the kind of thing you do when you have four of the same machine). However, on the other three machines the installation fails and the machine restarts. if I remove the harddrive from the 2.8ghz and place it in any of the other machines - even with the same bios settings selected - bootup fails. In both case, the installation and boot fail with the last line being displayed as: Using SMBIOS table found at 0x0 (hex value here) Using ACPI RSDP revision 0 found Starting Darwin/x86 I had replaced all four mother boards in the 270s with replacemnt board provided by Dell. Of the four boards, one was an actual brand new board. The other three were refurbished. I don't remember which machine I put the new board in, but I have a hunch it was the 2.8ghz machine. This morning I started looking around across the boards and noticed that the chip in the upper right corner of the mother board is different on different boards (i've attached a picture of the chip in question). On the 2.8ghz machine, that chip has a different revision than any of the other boards. On Machines A & B, that chip has a different revision than any of the other boards. On Machine C, that chip has a different revision than any of the other boards. I actually have one spare refurb board and that chip has a different revision than any of the other boards. I'll post the chip numbers when I can, but I suspect that if this chip is different, other aspects of the boards might be different too. This explains why many people are having different results with the 270s. And in my case, it probably explains why only 1 of my 4 machines will run OS-X properly. If you have a GX-270, post the revision number of the chip, and let me know whether your OS-X installation works properly or not. Also, note your BIOS version and any BIOS settings you changed. Note: none of the options, such as -v -x -s etc make any difference. Link to comment Share on other sites More sharing options...
fyaajster Posted April 14, 2008 Share Posted April 14, 2008 Here is my model GX270 LPC47m534 B0406-C935 8G116686B Why don't you try the new Kalyway v.10.5.2 everything work fine for my GX270 except the graphic. I have sound,ehternet no graphic. Did you get your default grahic working let me know. Link to comment Share on other sites More sharing options...
Gujal Posted April 14, 2008 Share Posted April 14, 2008 hmm, the 2.8GHz and 3.0GHz is a clue I think. is 2.8 Northwood and 3.0 Prescott? Cos the 3GHz if Prescott has HyperThreading enabled which is a strict no-no for any OS other than XP. You should have an option in BIOS to disable Hyperthreading. Disable it and give it a try Link to comment Share on other sites More sharing options...
PopeOnABomb Posted April 15, 2008 Author Share Posted April 15, 2008 So far my machines are: LPC47m534 B0406-C935 8G116745B LPC47m534 B0406-C935 8G113791A There is an option for Hyperthreading on 3.0ghz machines, but even when disabled the result is the same. Also, the 10.5.2 install does not work either. It encounters the same errors as the 10.5.1. I wonder how many people with GX 270s installed it on a 2.8ghz chip versus a 3.0ghz chip.

PopeOnABomb Posted April 15, 2008 Author Share Posted April 15, 2008 The problem is arising from the different controller chips on the motherboards. So, it is either hit or miss. On the chance that this is Kalyway specific, I'll post my results once I've tried the newest JaS release and Leo4All. Link to comment Share on other sites More sharing options...
PopeOnABomb Posted April 16, 2008 Author Share Posted April 16, 2008 I tried the newest JaS DVD as well as the newest Leo4Allv2. These both caused the same reset, but Leo4Allv2 caused the machine to get stuck in a cycle of reseting. By this I mean the machine reset and before fully posting reset again. This continues until I pulled the power cable. Link to comment Share on other sites More sharing options...
quietthomas Posted December 3, 2008 Share Posted December 3, 2008 I just found this out, and thought of this post when I did: Disk Utility's 'erase' option DOESN'T REALLY WORK! Meaning, that the errors, faults, and incorrect install options from previous installs MAY carry over to fresh installs. This may explain why your GX270s APPEAR to have inconsistent installs! Basically you have to find another way to format them before you re-install! TOOK ME 5 DAYS OF INSTALLATIONS TO WORK THIS OUT! Link to comment Share on other sites More sharing options...
