Add one more hard drive to the list that stalls Chameleon...
Anytime I plug in my 640GB Seagate ST3640323AS (firmware is updated and in good shape per diagnostics), it'll stall Chameleon 2.0 of any flavor (RC1 - RC3), or also Netkas' PC EFI 10.3.
The bootloader will not even make it to the GUI, but instead gets stuck at the spinning cursor immediately before (take your pick of the following characters \ | / -- ).
It doesn't matter if I'm trying to run Chameleon from a USB stick, AHCI SATA HDD, or Optical drive (also sata).
If I yank out the ST3640323AS, then all is fine.
Interestingly, that same incompatible drive is perfectly fine (it actually has been serving as my Time Machine Backup over the past ~year or so) on my current stable setup running Chameleon 1.0.12 + PC EFI V9 to boot Leopard 10.5.8 from a 2-disk raid0 setup (two Seagate ST32050410AS).
I have a fourth drive (ST3320620AS) that I've been using as a controlled environment to try Snow Leopard, running Chameleon 2 RC3, actually with Netkas' PC EFI 10.3, and custom DSDT.aml. Works great with any combination of drives plugged in, as long as the aforementioned incompatible 640GB drive is yanked out.
(I'm not partial to Seagate drives, by the way, they just happen to sale when I'm looking to buy)
