Hello,
I tried to install Haiku R1 Alpha 2 on a notebook and I failed.
I used the boot CD. The MD5 is OK.
Notebook:
Samsung R40 Plus
Intel Core Duo CPU
2 GB RAM
ATI XPRESS Radeon 1250
The system fails to boot from the boot CD.
The boot screen loads and progeresses until the last icon (the rocket).
Sometimes even the blue desktop screen appaers (but it is empty). After
that
nothing happens.
There is no error message. It seems that the system simply stops.
The R1 Alpha 1 works fine on this notebook.
Today I found the source of the problem.
When I deactivate the second CPU core in the BIOS of the notebook, then I
can start and use Haiku Alpha 2.
By the way, I have the same problem with the newest nightly build.
Please note that I tried all options in the safe mode and I deactivated
the power management, the LAN, the wireless functions and almost anything
that I could find in the BIOS configuration and the Haiku safe boot menu.
Nothing helped.
Only when I deactivate the second CPU core, then Haiku Alpha 2 runs, even
when all the other features are activated.
Why is this so?
The Haiku Alpha 1 version runs wonderful on this notebook, even with both
CPU cores.
What was changes between Alpha 1 and Alpha 2 that could cause such a
problem?
Best wishes,
Miroslav
