*# FUNCTION NAME: startc
*#
*# PARAMETERS : None
*#
*# RETURNS : Nothing
*#
*# SIDE EFFECTS :
*#
*# DESCRIPTION : Is called from the startup assembler file of the
*# box, after initialization of registers, stack pointers etc.
*# Performs a copy of data from PROM into RAM, then starts
*# the OS.
*#
*#---------------------------------------------------------------------------
*# HISTORY
*#
*# DATE NAME CHANGES
*# ---- ---- -------
*# Jun 12 1995 Jens Johansson Added 530 fix. After the analog ethernet
*# circuit was replaced with the same circuit
*# as in the 550r, the reset signal was NOT
*# taken from the same pin (P15), but from TXD2
*# instead. It is set to low here.
*# Jun 20 1995 Jens Johansson Hardware is the same now. The above fix
*# removed.
*# Nov 30 1995 Sven Ekstrom Added unconditional printout of product
*# name, version, and creation information.
*#
