Hi all,

I'd like to update my imaging server with "ZDM7SP1IR3a_HP1-October_08.zip".
I have to do this.

PXE files:
1.Take the back-up of the existing 'initrd','root' and 'linux'.
2.Copy the new pxe files and (on Linux) give read and execute permissions to all users.
3.Boot the managed device through PXE.

Can anyone help me with the "(on Linux) give read and execute permissions to all users" part.
I know it's a noob question but I've tried to change the permissions using Mac OSX terminal but when I copy the files on the server it seems that the pernissions are not correct.

The result being a faillure when the initrd files loads on a HP dc7100

Thanks for helping the noobish noob that I am.
