open boot drivers vs operating system drivers


Hi,

upon some readings i got to know that sun openboot contains an forth
language interpreter and openboot provides device drivers for attached
devices like scsi etc. My questions is as openboot already providing
drivers for attached devices
then whats the need for sun operating system to load again new device
drivers
upon booting ? can;t it use openboot device drivers to handle attached
devices ?

can we write forth programs and use openboot to execute at openboot
prompt ?
suppose i want to read a file "abc" from harddisk at openboot prompt.
Is itpossible ? as openboot will contain driver for attached harddisk ,
for how it knows about file system ?

please clarify me
-Thanks for your time
Ravi

Solaris can't use openboot drivers, as openboot is not Solaris, and is fact cannot even be qualified as an operating system, it is a "monitor", or single program running on top of the hardware, without an O/S layer.
Driver's APIs are thus different.

you certainly can. this is documented in the openboot command reference manuals.

I don't think there is a command to load a forth script file from disk to be executed, nor to allow the forth script to read data from a text file, but I may be wrong.
The load command, howerver, allow to load and run a binary file.
