How to safely and effectively refresh the bios at my Asus Eee PC 1001HA?

[Bas Roufs]

Dear forum members

So far, my attempts to "flash"/ refresh the bios of my netbook failed.
My netbook is an Asus Eee PC 1001HA, with a dual boot configuration:
Kubuntu 9.10 netbook remix and Win7. I tried 3 methods proposed by
Asus:
at the Windows partition, via some special bios update tool;
with MS-DOS or Freedos at bootable CD's and USB sticks, in combination
with the latest version of the so-called 'afudos' utility;
with "EZ flash", also together with a bootable USB or CD.
None of the 3 methods has worked so far in my case.
Does anybody have experience with any method which effectively helps
to refresh the bios of some Asus Eee PC?

Thx. for replying,

Bas Roufs.
