Did you run as admin? Have you checked your SLIC with RW? which version did you use? The dos or Windows?
If your Dell model was never offered with Vista, then the modding cannot be done (it's really complex from what I read so far). This is true for Optiplex machines older than 745/320/etc (e.g. GX620/210L), Latitude machines older than D620/D520/etc (e.g. D610, D810, D600, D505), and so on.
I have installed Dell 1555 bios given here.. but win 7 is not activated?? how to do so?? n00b here :*(
i modded that bios. But i don't have that laptop. I need someone take a look that is correct or not. Just practice to mod phoenix bios.
There is always some element of risk when flashing a bios and flashing a modded bios does have an additional level of risk, if you can't accept or do not want to accept that risk don't flash. That said, These bioses are nearly identical, the model numbers and versions are the same only the SLIC should be changed. Other than that you should notice no changes. There is always a risk of "bricking" your PC. I regularily flash back and forth to my "stock" Dell bios when testing on my machine
Go with the dos package, or the newer win/dos compatable version. Those ones work remember IMPORTANT INFORMATION REGARDING THIS INSTALLATION METHOD Please close all programs before executing the Windows NT-based installer. Due to the somewhat increased risk of errors updating the BIOS from within Windows (as compared to using the boot diskette method), it is HIGHLY recommended that the computer be connected to AC power via the AC adapter, and that the power-save mode is set to 'Full Power' or the equivalent while installing the BIOS. The Windows NT-based installer requires Administrator priveleges on the target system
