[Unattended] Initrd modifications

Hello,

 

I am a bit of a newbie in Linux.

 

I want to open the initrd that comes with unattended's Linux boot, on a windows machine to look around.

 

I was led to believe that most ramdisk images we gZipped.

 

My copy of Winzip should open this but it can't.

 

Can you point me in the right direction?

 

Thanks for any help you can give.
