Ok, my new (used) Lenovo X61s works great!
patched ACPI.PSD ver. 3.22.06
In config.sys:
PSD=ACPI.PSD /VW /ST=0
In os2ldr.ini:
os4krnl = OS4KRNL using config.os4,LOGSIZE=4096,CFGEXT=OS4,VALIMIT=3072
Works still in progress
!
I'll submit comport.log asap
After, we'll try the desktop, i need a null-modem cable.
Thanks!
