[Sussex] Centos 6 64bit no longer bootable

[John Crowhurst]

Hi,

You may need to check to see if the server has a 64 bit processor, 
because it could be 32 bit and the install media works with both 32 and 
64 bit. Boot into recovery mode and type uname -a to check to see what 
the kernel is running. Also cat /proc/cpu will tell you what CPU the 
kernel detects.

Best,

John
