The X68000 has 16KB of battery-backed SRAM, which is used to store basic system settings. It can also store drivers or small programs. Since it's battery-backed, and since the batteries that shipped in most X68000s are a decade or two past their useable life, this will cause some problems. Symptoms of a dead or dying battery include loss of settings, the Generic Error, and loss of whatever program was stored in the SRAM. | The X68000 has 16KB of battery-backed SRAM, which is used to store basic system settings.

If you have an older machine the process is more involved. You'll need a debugger of some kind.

Boot the first disk (an image is in the archive called "XC2101I.LZH"). After answering "N" to the prompt that pops up it should dump you back in HumanOS. Then type: | If you have an older machine the process is more involved. You have two options: |
