Memory Size

The first five sections of SW2 tell the system how much user memory you have.
Don't forget to change these sections if you add more memory. There is also
a memory block select jumper on the memory card which must be configured
if you add a second card. Details will be included with the installation instructions
for the add-on card.
Autoboot from Selected Drive
Sections 5 and 6 determine if the operating system is to be autobooted from
the Winchester drive or floppy drive. If neither autoboot option is selected (sections
5 and 6 are both left, or both right), autoboot is not performed, and the operating
system must be booted manually.
