Jemm386 v5.8 - alternate reset port and reset value (Developers)

Hi, nice to see you finally solved your reboot problem.
It seems that KBC on your MB may cut off some legacy features that doesn't route reset signal properly and the system relies on ACPI (today view on OS requirements - it must support ACPI to use advanced features of HW)

I tried your tool and it displayed:

Detected ACPI interface in version 1.0
Physical processor cores: 4
Logical processor cores: 4

Values for coldboot as ACPI reports:
io: 2562 (0A02h)
mmio: 0 (00h)
value: 0 (00h)


But when I send 0 to port A02h it does nothing. Maybe my MB is not crippled enough so it has working legacy reset but no ACPI reset :P

Your proposal of altboot option for JEMM seems to me OK and easy to implement instead of adding ACPI code for autoprobe - that we see is not reliable, yet ;)

DOS gives me freedom to unlimited HW access.
