I'm adding a 2.2 slic to HP's Microserver N36L/N40L bios using AMITool. I'm pretty sure that I read somewhere that the method to add the slic was to choose SSV2 and select in Advanced: Only alter RSDT and XSDT tables Ignore checksum and module 80h warnings I've done this but I'm still getting "Boot block checksum not valid" messages when I press Go in AMITool. I'm a bit worried I may end up with a bios that will brick my board. Can anyone confirm I'm doing it right and it's safe to ignore the messages. Thanks.
