Vista Ultimate x64 on Sony Vaio VGC-RM1N - Blue screen during install

Hi there,

I tried to install the 64-bit version of Vista Ultimate on a Sony Vaio
VGC-RM1N but unfortunately I got a 'blue screen of death' shortly after
the installation starts, with the following error:

STOP 0x0000000A IRQL_NOT_LESS_OR_EQUAL

I tried again but also pressed the 'F8' key to run setup in safe mode,
and was then able to see the drivers being loaded. The blue screen seems
to happen when the 'disk.sys' driver is being loaded.

Has anyone else with this Vaio tried to install a 64-bit version of
Vista and seen the same problem? If so, did you manage to solve the
problem and install sucessfully?

Thanks

Just an update on the above problem.. I managed to workaround the STOP
error and install Vista x64 sucessfully by disabling the "Core
Multiplexing Technology" option in the BIOS.

Unfortunately, I realised later that although disabling this option
allowed Vista to boot ok, it effectively disables two of the four cores
in my CPU; so this isn't a very good solution!

As a result of this discovery, I now suspect the problem is due to a
BIOS issue, but as this is a Sony VAIO (and x64 Vista is not officially
supported by them on my model) I may be waiting quite a while for an
updated BIOS.

seems like i'm not the only one having this problem, though mine's a desktop
running on quad core too. haven't tried taking out the multiplexing in the
bios, but i'll do it later and see if it works.

after installing your vista, if you enable the multiplexing, does it still
work?

Unfortunately not - although I can install Vista x64 with the
multiplexing option disabled, if I try and re-enable it once the
installation is complete I get the same blue screen error.

I am convinced that the problem is a bios issue specific to this Vaio
model. Unforunately no bios updates have been released by Sony as yet
(and this is unlikely to happen in the near future given that they don't
officially support Vista x64 on this model)..
