Did you check rom holes inside modules extracted by Phoenix Bios Editor ? Maybe my question is a stupid question, but in the past I found that some SLIC calls (and RSDT pointers) are inside module and not enabled due to holes.
Boost, I have a question, was your laptop not originally a Vista OEM laptop?, should it not already be SLIC 2.0 enabled? Sorry if it isn't. but here in Canada I don't believe they even sell it without Vista... At least not from what I remember, of course I could very well be wrong.
@ Boost, ok, I was just asking. You see I have a pre-Vista Inspiron 6400, the model was sold before Vista came out, but was also sold with Vista pre-installed once Vista was released. I only had to update to the latest bios and I had no problems. I am interested in all this because the odds of Dell updating it to SLIC 2.1 now for me is zero, so I am starting to watch these forums closely, hoping that Yen or someone comes up with a way to switch the 2.0 SLIC for 2.1. Best of luck and BTW those asset pass and service tag programs do nothing on my laptop either, except change the service tag.... It says the Eeprom is erased, but I don't see anything to suggest the bios goes in some sort of repair mode...I am interested though in what Yen is doing with capturing bios files from the ram memory as I am sure that my bios update files extract to ram and flash from ram as well. Perhaps they are decoded already in ram and he will be able to save the file with WinHex and work with the SLIC. Perhaps once the bios is obtained and flashed with WinPhlash the modules will be activated? Anyways, once again, best of luck, perhaps if that works for you, there may be hope for me as well. If you do run in a little trouble, mine won't flash anymore with the Dell windows flasher, but mine will still flash in dos, so if it gets messed up and won't flash back in windows, but will boot, try flashing back with the flasher in dos as mine seems more flash friendly in dos, yours may be as well
It's a big difference if the Notebook / PC has an enabled factory SLIC just to update to marker 2.1 OR to introduce a complete new SLIC to a Notebook /PC which has got no factory SLIC enabled. At first case you just have to exchange the existing factory marker. At second case you have to disable unusable factory SLIC and to introduce a complete new SLIC module, which is always a more complex operation to realise.
