Machine is a Lenovo T61 Laptop running Windows XP Professional.
The process of installing an embeded partition sets up a DOS pre-boot environment.
When the PC boots into the DOS partition, it attempts to setup the DOS environment using high memory.
Thus HIMEM.SYS attempts to use "A20 Line" as its control method. But this appears to fail to install correctly.
Subsequent use of the BWINST.EXE and FIRM.EXE tools, all complain "DOS/32A fatal (0007): Could not enable A20 line".
Does anyone have a solution to this issue or a better embedded automation partition installation process? Ideally something that is going to be portable across more models of machines. :)
