Running ROMless
As of version 1.2.0, LisaEm no longer requires the Lisa Boot ROM in order to start an
operating system, such as the Lisa Office System. If you do not have a proper boot ROM file,
simply leave the Lisa ROM field underneath the config tab of Preferences empty.
If you use a file that cannot be found, or have no access to as a boot ROM, LisaEm will run
ROMless, and present the ROMless Boot dialog below.
If you pick an invalid or corrupted file, LisaEm may crash if you attempt to power it on!
When you attempt to power on the virtual Lisa, you'll see the following dialog box:
You can now boot from the Floppy drive, or the ProFile hard drive on the Parallel Port.
Booting from a floppy image:
If you've selected the floppy drive, and a floppy has been inserted into the Floppy drive before
attempting to power on the virtual Lisa, LisaEm will boot from it. Otherwise, a dialog box will
appear asking for a floppy disk image to boot from. You will of course only be able to boot
from valid bootable Lisa disk images such as the Lisa Office System 1 diskette.
Booting from the ProFile hard drive:
You will be able to boot from a Profile if the virtual Lisa has been configured, and has the
Parallel Port under the ports tab of Preferences set to Profile, and the Profile disk image it
points to has a valid OS installed.
Booting from Profile drives attached to expansion port slots is not possible when running
ROMless. To do that, you would need both the Lisa Boot ROM and the Dual Parallel ROM.
Danger: Do not mix the ROMless and ROMed modes with existing Lisa Operating Systems.
This may lead to troubling issues such as the 10738 OS error. Install LOS ROMless if you
want to run ROMless. To be safe, always keep backups of all your disk and Profile images.
