OK, so I spend the last 24 hours (with a little bit of sleep in there somewhere) trying to get my 1340 to install Snow Leopard, to no avail.
First I tried booting with the 1340 boot-132 CD mentioned in post #1, swapping my retail SL DVD shows up as APPLE_HFS and gives several "HFS Signature not present" errors then says "Can't find Mach Kernel".
I then tried restoring my DVD to a USB key, and booting the boot132 CD with the USB key plugged in. That at least shows up, as the proper name, so I boot from that, and the it gets to initializing AppleIntelCPUPowerManagement and then says "still waiting for root device". USB Key is pulsing, which means it's not mounted.
Third, I thought, "OK, fine. I'll boot directly from the USB key." So I copy the kexts and whatnot from the Preboot image on the boot 132 CD (I also tried adding all the necessary ones manually from post #1), install Chameleon, boot from the USB key, choose it in the Chameleon menu, wait for the installer to load, and when it finally does, I choose Disk Utility to partition my HD, and suddenly I get the dreaded spinning beach-ball, and my USB key goes from the nice flashing activity light to the pulsing that means it's not mounted anymore. The system sits there until I give up and force it off.
I then tried using [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url], which kernel panics somewhere in the graphics driver kexts.
Then I tried downgrading my CD drive firmware to DW10 (from DW50), but I got the same error as the first time. Any ideas about why I am having so much more trouble than others? I know my SL disk is good. It's a real retail disk, purchased from Apple, and I've used it to installl SL on other computers. I have had SL running on this laptop, but I did it from a Leopard install, and I don't have one of those anymore. I guess I can always install a temporary Leo install and use that to do an upgrade again, but it seems silly when so many have installed this correctly.
Sorry if this is a repeat of a previous problem. I read through this thread as best I can, but I may have missed a post along the way. If so, I'd appreciate even a simple "there's something a few pages back, look again".
Thanks in advance for any help!
Edit: Just in case it matters, my computer's specs are as follows:
2.53Ghz C2D P8700
GeForce 9200M GS (the funny hybrid-sli one) with 256M dedicated graphics RAM
Dell Wideless 1510 Wireless-N card
Atheros AR5008X Wireless-N card
500 GB HD.
