398	Boot with ACPI is unstable	LarsErdmann	pasha	"Configuration:
eCS 1.2 R German with all fixes applied
ACPI 3.14
APM 1.28
Kernel: @#IBM:14.104a#@_W4  IBM OS/2 Kernel
Single CPU Mainboard

I have been trying various switches to ACPI, alone and in combination:
/FS /VBE /EIS /OS=""Microsoft Windows"" /!NOD /PIC

but the boot is unreliable, sometimes it hangs when loading the .SNP files, sometimes when loading the BASEDEVS (.SYS,.ADD.FLT,.DMD)

Notes:
a.) I have been using /OS=""Microsoft Windows"" as I ran iasl.exe as described in doc and generated .dsl file as described in documentation, find attached. Since it contained a conditional on OS type ""Microsoft Windows"" I thought it would make a difference but it did not
b.) /!NOD does not seem to do anything. Even after adding /!NOD, drivers ACPICA$ and OEMHLP$ reside in the same loaded module (Theseus tells me that) and that module is ACPI.PSD. Adding /!NOD I had the expectation that OEMHLP$ would be taken from the kernel module (where it resides per default) but it is not.
c.) I am also running WinXP on this machine (via OS/2 bootmanager). Rebooting from WinXP into eCS seems to be problematic. It seems to trigger the boot hang or at least negatively impact it. I guess WinXP leaves ACPI in some state that makes ACPI.PSD unhappy.

Find attached the config.sys file, the .dsl file, the ACPI and APM log files.
