-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.

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. Sometimes the battery can leak, causing damage to the PCB so it is highly advisable to replace it or change it for something more safer. It is a GB50H-3 50mAh 3.6V battery which can be replaced with a CR-2032 along with a battery holder.
  
 Sometimes the SRAM can get corrupted. This can either be caused by a virus, a dying (but not completely dead) battery, or a sloppily-written program crashing and vomiting all over the SRAM space. If the SRAM is corrupted, you will get this message at boot time instead of a normal "insert disk" screen: Sometimes the SRAM can get corrupted.
