I just compiled dmidecode with the latest stable version of cygwin.
The binary works fine on XP, but on Windows 2003, it throws a
permission denied error on accessing /dev/mem.
I searched the Cygwin list and found this message:
Accessing \device\physicalmemory from privileged
user mode processes works only on NT4, W2K and XP. Starting with 2K3,
access to physical memory has been restricted to work only in kernel
On the other hand, a patched version of dmidecode (not needing Cygwin
DLL) works just fine on Windows 2003.
Is there a workaround for /dev/mem: permission denied problem in Cygwin?
