Installing and Configuring Enhanced OS-9
Enhanced OS-9 for X86 PCAT 125
In order for a user state program to be granted I/O port access by
GIMMEIO, the user state program module must be supervisor state
(owned by 0.x).
NoteNote
Although the GIMMEIO trap handler was required as of v2.1 of OS-9 for
X86, users may now disable I/O protection system wide if desired, by
selecting Allow User State I/O in the Configuration Wizard’s Init Options
dialog box.
LOOP

Usage: loop -?
Usage: loop [-t] [-n<count>] [-m] [-s<count>] [<prog>] [..<progx>]
