Re: Installation on Intel DH57JG Mini ITX (Core i3 530)
Hi Snow,
Ermm, yes, I think I recall reading on the blog that it's possible to boot into working 10.6.0, then upgrade. In theory it'll work.
However, you do run the risk that smth breaks which would be a lot of hassle to fix, you'd be into terminal/single user land.
I'd either follow Tony's guide 100%, or build it up slowly (ie: DIY) with bare min needed to boot off HD in 10.6.0 (fakesmc, DSDT, smbios.plist etc) then you know what kexts you added or may need to remove when upgrading (EDIT: removed to avoid further confusion!). Just depends on whether you want to play & understand what's going on under the hood, or just have a (hopefully) no-hassle experience.
I favor the DIY approach, esp if you have a graphics card that is not known to be a 100% "just works" one.
To change Chameleon options, you need to edit the com.Boot.apple.plist in /Extra.
Chameleon release notes (from Chameleon web site, or I think in the case you used Tony's iso, Asere's web site for AsereBLNv1.19 spin on Chameleon) has read me's showing all the options available. Specifically, in the .plist you can change the Timeout value for the countdown, or remove the relevant <key> <string> lines entirely.
But until the installation is all nice and working, I'd keep the timer as-is, so you can more easily dive into verbose boot etc in case of problems.
