If you've enabled the PtvioShell, you can press a key early in the boot process to enter a monitor-like environment. The 4.3 ROM image has removed the help screen from this, though; the help screen from the 4.1 image was:
? - print this list
@ - boot (load and go)
p - print boot params
c - change boot params
l - load boot file
g adrs - go to adrs
d adrs[,n] - display memory
m adrs - modify memory
f adrs, nbytes, value - fill memory
t adrs, adrs, nbytes - copy memory
e - print fatal exception
n netif - print network interface device address
$dev(0,procnum)host:/file h=# e=# b=# g=# u=usr [pw=passwd] f=#
tn=targetname s=script o=other
boot device: udma=drive,boot par file name: /udma0/vxWorks
Boot flags:
0x02 - load local system symbols
0x04 - don't autoboot
0x08 - quick autoboot (no countdown)
0x20 - disable login security
0x40 - use dhcp to get boot parameters
0x80 - use tftp to get boot image
0x100 - use proxy arp
