[LinuxBIOS] OLPC hardware specification information

[jardel at lesc.ufc.br]

Dear Sir,

   If you permit me answer,

   VSA (Virtual System Architecture) is an AMD technology that grants the
compatibility of AMD GEODE with i386 systems. VSA is composed of
various VSMs (Virtual Support Modules). XpressGRAPHICS and XpressAUDIO
are VSMs. The following VSMs are described in the document VSA
ADAPTATION GUIDE of AMD:

AUDIO VSM (XpressAUDIO)
LEGACY VSM
PM CORE VSM
APM VSM
ACPI VSM
RTC VSM
SOGTVGA VSM  (XpressGRAPHICS)
KEYBOARD VSM
OHCI VSM
UART VSM


Thanks.


Jardel.
