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. |
