6 Modifying the Environment

Auto Boot Abort Delay = 7?

The time in seconds that the Autoboot sequence will delay before starting the boot. The purpose for the delay is to allow you the option of stopping the boot by use of the BREAK key. The time value is from 0-255 seconds. (Default = 7 seconds)

Auto Boot Default String [NULL for an empty string] = ?

You may specify a string (filename) which is passed on to the code being booted. The maximum length of this string is 16 characters. (Default = null string)

ROM Boot Enable [Y/N] = N?

YThe ROMboot function is enabled.

NThe ROMboot function is disabled. (Default)

ROM Boot at power-up only [Y/N] = Y?

YROMboot is attempted at power-up only. (Default)

NROMboot is attempted at any reset.

ROM Boot Abort Delay = 5?

The time in seconds that the ROMboot sequence will delay before starting the boot. The purpose for the delay is to allow you the option of stopping the boot by use of the BREAK key. The time value is from 0-255 seconds. (Default = 5 seconds)

ROM Boot Direct Starting Address = FFF00000?

The first location tested when PPCBug searches for a ROMboot module. (Default = $FFF00000)

ROM Boot Direct Ending Address = FFFFFFFC?

The last location tested when PPCBug searches for a ROMboot module. (Default = $FFFFFFFC)

Network Auto Boot Enable [Y/N] = N?

YThe Network Auto Boot (NETboot) function is enabled.

NThe NETboot function is disabled. (Default)

Network Auto Boot at power-up only [Y/N] = N?

YNETboot is attempted at power-up reset only.

NNETboot is attempted at any reset. (Default)

Network Auto Boot Controller LUN = 00?

Refer to the PPCBug Firmware Package User’s Manual for a listing of network controller modules currently supported by PPCBug. (Default = $00)

Network Auto Boot Device LUN = 00?
