Known Issues with the x86 ROM Boot Loader (Windows Embedded CE 6.0)

1/5/2010

The following issues are encountered when using the boot loader in the default configuration. Many of the issues are because of the lack of a BIOS.

Issue Suggestion

DRAM sizing

The configuration code does not perform DRAM sizing. Currently, the implementation supports and has been tested on 32-MB and 128-MB configurations.

The DRAM configuration needs to be statically defined at build time.

VGA linear framebuffer (Flat) video driver

The boot loader does not support the flat video driver because there is no VESA BIOS implementation.

Therefore, the hardware platform's native driver, or the VGA driver, should be used.

MediaGX audio

The audio function on the MediaGX companion (CS5530/A) is not supported.

The audio implementation makes use of a software library, the Virtual System Architecture (VSA), which is normally implemented as part of the BIOS but is not included in the boot loader code.
