Thanks for this fantastic forum!!! I found modded BIOS's for all of my systems here, but the final "machine" I want to work with SLIC 2.1 is my VMware ESX Server to have the 2.1 SLIC. I know there has been a (Binbin) BIOS around somewhere but that one doesn't work with Version 7 VM's and only has the 2.0 SLIC. In the past (for Vista and W2K8) I've used the tutorial to put in the _ASUS_Notebook SLIC 2.0 which worked like a charm. I used the most recent BIOS included in VMware Workstation 6.5. It seems however, that this tut doesn't work anymore for SLIC 2.1. I would like to try and mod this BIOS myself, but if someone could put me in the right direction that would be great. What I've done so far: I've used the instructions in the tutorial and modified the SLIC to match "DELL " and "M09 " I've copied the DELL.BIN to the TEMP folder of the Phoenix BIOS editor. I've modified the ROM.SCR I modified a DMI string (replaced "VMware Inc." to "VMware Inc" I have built the BIOS I put in the "bios440.filename" option, and I CAN see SLIC inside ACPI when I run RW-Everything. The original BIOS doesn't show that tab. I have installed both the OEM key and the DELL cert. It still says "28 days to activate" I know there is a Phoenix topic on this forum, but it is closed, so that's why I'm posting it here. Hope someone is able to help me out here. Thanks a million.
