Need a little help here to figure out what's going on... Until recently I had a working hack of my ESXi server using this wonderful app (EsxBiosTools.v1.1.2): //forums.mydigitallife.net/threads/12982-ESX-ESXi-Bios-Tools (Request to mod - Please sticky that thread.) Many thanks to pix for this awesome tool. Unfortunately, my last update to version ESXi 4.1 320137 changed this. Since updating, my repeated attempts to get a working SLIC mod have failed. The tool seems to work fine and reports success with no errors. I can inject a modded bios and extracting the bios afterward shows that it is indeed modded. I have tried multiple BIOS for different OEM's, all V3.15 - no luck. Even though the bios IS modded and shows SLIC 2.1; I get a DUMP Error from within any VM. I don't know enough to speak with any sort of clue here but it appears that vmware is blocking the altered bios. Am I using the wrong BIOS version perhaps? Any help would be appreciated.
