+'''Status:'''

+Uninitiated.
+
+'''Introduction:''' 
+
+This project involves addressing a few deficiencies in the existing pc386 BSP as well as improving it so it supports non-legacy hardware configurations.
+
+'''Goal:''' 
+
+To have a functioning pc386 BSP that can operate on PCs without legacy BIOS or peripherals. It needs to support all features of RTEMS including SMP and Thread Local Storage.
+
+'''Requirements:''' 
+
+* Knowledge of x86 ASM, C Programming language.
+* Run on non-legacy hardware configurations.
+* Share code as possible with new x86_64 BSP (when exists).
+* Add Thread Local Storage support to x86 (#2468)
+* Thread migration is broken on SMP on x86 (#2183)
+
+There are at least the following tasks identified related to support of non-legacy PC configurations. A non-legacy PC appears to be one in which at least EFI is used instead of BIOS.
+
+* Support video on non-legacy systems.
+** Probe for video is known to fail on non-legacy systems.
+* Support PCI on non-legacy systems.
+** Probe for PCI BIOS is known to fail on non-legacy systems. It is expected that PCI bus access routines will need to be provided for non-legacy configurations. 
+* Support for APIC rather than legacy PIC.
+
+It is a requirement for code to be shared with x86_64 when that is supported. It is also a requirement for the pc386 BSP to support both legacy and non-legacy and decide what to do at run-time. 
+
+'''Resources:''' 
+
+* Current RTEMS developers. 
+* Do not reinvent the wheel and use existing code instead, e.g. from FreeBSD.
+
+'''Acknowledgements''' 
+ *  TBD
