System Controller Hub (SCH) is a family of
Intel microchips employed in
chipsets for low-power
Atom-based platforms. Its architecture is consistent with the
Intel Hub Architecture but combines the traditional
northbridge and
southbridge functions into a single
microchip.
Poulsbo
Poulsbo is the codename of the first SCH and plays a key role in
Intel's second-generation Menlow
UMPC and
MID platform chipset for
Atom Silverthorne
The Town of Silverthorne is a home rule municipality in Summit County, Colorado. According to the 2010 Census, the population of the city is 3,887.

The town was named for Judge Marshall Silverthorn who served as the judge of the mine ...
microprocessors.
The graphics core is called
GMA 500 and unlike most graphics cores used by Intel was developed by
Imagination Technologies. Intel licensed the
PowerVR SGX 535 as a graphics core and the PowerVR VXD370 for
H.264/MPEG-4 AVC playback. The video core is able to process
720p as well as
1080i
1080i (also known as Full HD or BT.709) is a combination of frame resolution and scan type. 1080i is used in high-definition television (HDTV) and high-definition video. The number "1080" refers to the number of horizontal lines on the screen. ...

and
Dell Inspiron Mini 12, among others), Poulsbo's graphics core GMA 500 is currently not well supported by Intel for Linux.
A proprietary driver was shipped with Dell's adaptation of
Ubuntu 8.04.1 Netbook Remix, which provides 2D hardware acceleration (although users reported serious stability issues) under Linux kernel 2.6.24.
A work-in-progress free driver is currently available, however the proprietary driver does not work with current Linux kernels and current versions of X. Work is under way to provide at least 2D support in current Linux kernels, although this will still rely on proprietary binary code for the 3D part of the driver. The current status of this driver runs on Fedora 10 and allows for 2D. 3D acceleration, however, is still broken.
A working, proprietary driver package is available for Fedora 11.
Starting with Mandriva 2010 Release Candidate 2, Poulsbo drivers are now fully supported out of the box when you use One isos. Hardware will be automatically detected and configured using XFdrake. As it needs non-free firmware, this could not be included in Free isos.
A rudimentary (no 3D acceleration) driver was added to Linux 2.6.39.

Whitmore Lake is the codename of another SCH.
