/NOGUIBOOT in DS3.1

[Anticode]

I might think of two reasons:

1) To give you the opportunity to see the "Press Esc to cancel loading SOFTICE.."
2) The video driver has not been initialized yet so SI cannot use its universal driver, so if u want to use it at boot time, SI must use its text mode driver.
thats why there is a /NOGUIBOOT, to keep the display in text mode during the boot time
