asus k53ta

[seelyfam]

newbie.
I've got an asus k53ta.
i'm trying to do two things.
the first is update the bios from 207 to the current 214. should be simple but of course it's not. the utility for doing this at the asus site says i don't have an asus motherboard it won't run. stupid software, of course i have an asus motherboard inside my asus laptop!
it's an asustek with amd bridge rev.00 and southbridge amd a55/a6om according to cpz software and windows 7 info. its a quad cpu.
I can't follow the dos install routine on this site as it seems to be missing clear instructions for someone like me. I would much rather do it via windows anyway to eliminate any mistakes i might make.
r there any ideas on how i can get the asus software to recognize my asus laptop?
The second issue is i can't get the hdmi to output video; only the sound works. It worked before with this current bios version of 207. I did a new install of windows and all the updates but no there isn't any hdmi video. I have the chipset drivers loaded and it lists the correct video drivers as being there in system info.
Any help would be greatly appreciated.
thanx,
