University of British Columbia. The BSP is for:
Yes, this is the "entry model" of a series of boards from Technologic
Systems. Costs <$200 I believe. They have a WWW page at www.t-systems.com.
I am letting them know about the availability of this BSP too.

moves pieces of the pc386 bsp up to a shared level for all i386 BSPs
and modifies the i386ex BSP to use those shared pieces. Serial remote
debugging is included for both targets. Erik's notes:
There are several workarounds in it:
1) #define NEXT_GAS is hardcoded in pc386/start/start.s
2) #define NEXT_GAS is hardcoded in i386ex/start/start.s
3) #define NEW_GAS is hardcoded in pc386/start16.s
4) #undef __assert and redeclare _assert hardcoded in console.c for
both pc386 and i386ex due to my egcs1.1b ~ newlib problem. Should have
modified t-rtems.cfg ( no time )
I've tested pc386 with both video and serial consoles and GDB remote.
All work fine, except that GDB acts weird. ( re: other posting)
I hope this will work for you. It took quite some time to locate the
autoconf error. The remainder was just grunt work.
Unfortunately, I think I've unwound the removal of the IBMPCInitVideo
stuff. Sorry. I REALLY can't spend more time... I've been at this
conversion to 4.0 locally and updating the release since Sept. 8th, and
have yet to compile my network driver.... This is as much as I can do
right now.
I look forward to the next patch to really test i368ex. I did make sure
that the sample tests worked for pc386.

Please find attached the two files that have been changed relative to
980921 . The changes here are in the handling of the counter-timer used
as the basis for the rtems executive clock. For the most part, these
are housekeeping changes.
The PSCLK frequency change in start.s... was a part of several
bug-fixes. The fix improves executive clock and timer accuracy.
changes :
start.s -- All timers are disabled by the initialization routine
-- PSCLK ( used by clock and timers ) frequency changed to 1MHz
The clock_initialize routine now assumes that the PSCLK frequency is
exactly 1 MHz.
ckinit.c
Clock_isr -- removed division by 1000. Now use 'static'
variable -- clock_intial_isr_value -- to reset Clock_isrs variable.
clock_initialize -- moved counter timer initialization here. Values
used to configure the timer are totally dependent on
BSP_configuration.microseconds_per_tick ( and the PSCLK assumption).
Initializes clock_initial_isr_value used by th Clock_isr to reset
Clock_isrs.
clock_on -- no longer configures the timer, just enables it.
Since altering the number of sections in the BSP, I decided to give it a
good "once over" . The clock handling is now cleaner.
