3-10 IRIS OWNER’S GUIDE
SERIES 3000 Version 1.0
Booting the IRIS
Table 3-2 summarizes the PROM monitor commands. Table 3-3 lists the device
names recognized by the PROM monitor.
To boot through the PROM monitor, follow these steps:
1. Set the
Power
switch on the display monitor to
On
.
2. Set configuration switches 1 through 4 to the appropriate boot
device setting (see Table 3-1). The default boot device is the hard
disk, which has the setting “CCCC”.
3. Set switch 5 to
Closed
.
4. Set the
Power
switch on the cabinet front panel to
On
.
If the clock battery has run down, the system displays this ominous
message:
Power has been lost to the machine.
This message refers only to the clock, however.
The IRIS displays the PROM monitor prompt:
iris>
If the prompt does not appear, press the
Reset
button.
Wait 20 seconds for the disk to spin up to speed. (The boot will fail
if you don’t wait that long.)
5. To boot from the device specified by configuration switches 1
through 4, enter the letter b and press
RETURN
.
The IRIS reads the file defaultboot from the default device.
