В новой версии реализовано правильное программирование MTRR регистров,
и программирование PAT, если нет MTRR.
Это важно для пользователей Intel Core i3/i5/i7.
Позже изменения Panorama VESA будут продублированы в SNAP,
таким образом SNAP заработает на SMP компьютерах.
(Это и другие обновления доступны по подписке eComStation)
Panorama is slower then SNAP, but since the PMSHELL is such a
lightwheight shell a proper tuned VESA driver can get you VERY far in
terms of performance.
The newly published Panorama drivers proves that. Many many systems
that where slow with Panorama are now MUCH more responsive!
Right now for eCS 2.2 SNAP is not a topic for us to focus on with our
development team. We have the code and will return to this topic after
the release of eCS 2.2.
We hope to release this beta version in the next 2 to 3 weeks.
SNAP has exactly the same problems with slow performance on some
systems as Panorama had. the so called MTRR registers where setup
incorrectly and on some
SMP systems that can also lead to problems. On top of that there is
code in SNAP that scans the PCI bus looking for video card. This code
is broken on at least on test sytsem in the test lab at work.
Also some TRAP's occur we need to go back and fix does.
The changes in Panorama will be merged in time into SNAP so we fix the
slow video performance as wel. The whole point is that SNAP at this
moment is time is not very usefull until we have the MTRR/PAT stuff
sorted out. That with Panorama is now done! There might still be
issue's with this newly updated video drivers but most feedback is very
good!

Roderick wanted me to release a new Panorama driver sooner rather than later.
However, there are still numerous administrative issues that need to be resolved
before I can release an official version. Therefore I have made available a "preview"
version which you can download and try out.
Since a Panorama section of the BetaZone does not exist yet, I have temporarily
uploaded the preview Panorama driver to the ACPI section since that is the only
place where I have write permission. This is not the correct place for the Panorama
driver and it will be moved when a Panorama section is created.
You can download this preview version from your Software Subscription Services at
the Mensys website. Log in to Mensys with your Mensys login id and click the
Downloads link. Click the "Software Subscription Services for eComStation"
Download link and find the ACPI section. The Panorama driver should be listed there
until it is moved to its correct location.
You cannot report problems with this preview version. This is a preview version. Also,
the ticketing system for Panorama is not setup yet and it will take me some time to do
so. You must wait for a new announcement regarding a new Panorama version
and/or an announcement regarding the ability to report problems. I will not respond to
problem reports via e-mail.
