I have a Dell E520N (ubuntu) which I like to put SLIC 2.1 on. I have read and tried many things without success. I have flashed the latest 2.4.0 BIOS mod, however the SLIC Dump reports "SLIC OEM ID or Digital Signature Error". The SLIC version is 0.0, marker is invalidated. Read elsewhere that the SLIC table is not complete. I have read some people were able to either run the Dell asset or svctag tool and fix this problem. When I run these tools I get this error message "This machine does not support an asset/service tag". Attached is the RWE after the 2.4.0 mod. Please help. Thanks very much!
