[FIXED] Successfully installed Snow Leopard on external hard drive. Booting? No..

[Grewbacca]

Hey guys (and girls )

 

My friend gave me all the cds ([url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url], retail dvd) and instructions to install osx on a partition of my external hdd. Everything went well, but..

 

When I try to boot osx with [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url], it loads exactly 20 times this message:

 

EBIOS read error: Device Timeout

   Block 0x64044 Sectors 0

 

At the time the boot I can recognize my hdds green light suddenly turn off. So the problem seems to be that [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] cannot connect to my hdd.

 

Any advice from this community? At least I hope so!

Hey

 

Sorry for double-post, but I figured this out and want to share it for others, who may have the same problem.

 

When in [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] GUI where you can choose the OS to boot, move the selection over your OSX-installation and type:

 

EHCIacquire=No UHCIreset=No

 

Then press enter.

 

This prevents the hdd from turning off. Nothing else needed.
