Snow 10.6.7 on USB External Hard Drive with a HPDV7

[atlantisman87bis]

I've a virtual machine on virtualbox running very well with Snow Leopard 10.6.7

 

but i can't use my ATI Radeon Mobility 5470 and Disk access are little slow. so i would install my retail dvd on an external USB drive.

 

My config is :

 

Motherboard HP 144B intel HM55

 

Core i3 370M

 

4Go DDR3

 

HD Graphics and ATI Radeon Mobility 5470 with 512 Mo

 

RALINK RT3090

 

 

 

i'm trying to install my retail DVD 10.6.3 + ComboUpdate 10.6.7 + [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] but the external is not bootable. i've a cdrom with [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] but the external hdd is not view by [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]
