INVALID ADDRESS FOR MCP error on TSMCP #37

Open pkimpel opened 9 years ago

pkimpel commented 9 years ago

Two different cases of apparent damage to the system disk, causing the system to be non-bootable under Chrome and Opera (on H/L, they said INVALID ADDRESS FOR MCP).

This is typically a result of the bootstrap addresses in sector 0 of the disk being corrupted. Possible TSMCP bug, but not enough information to pursue at this time. May be related to #36. Will leave open for the time being.
