I have a Pawnshop Management System developed with Informix-SQL 2.10 perfectly running
under a DOS 6.22 virtual hard drive (Microsoft Virtual PC 2007) on Windows Vista Home
Premium SP2.

The (2GB) BIGDOS partition, including the MBR (Master Boot Record) is encapsulated inside
one Windows Vista .vhd file (102MB). Backup copies to a flash drive are done in less than 15
seconds.

With DOS FSHARE.EXE, I can share Windows Vista Drives/Devices/Folders from within the
DOS virtual machine and vice-versa!

Examples:

LASTDRIVE=Z:

DOS Drive F: = Windows Vista Drive F:(USB Flash Drive).
DOS Drive L: = W.V. Parallel Printer (LPT1:)
DOS Drive P: = W.V. USB HP-LaserJet Printer.
DOS Drive S: = W.V. Drive C:
DOS Drive X: = W.V. C:\Users\Root\Desktop\Xfer

*CAVEAT: However, trying to UPGRADE to INFORMIX v.4.10 is causing me DOS16M problem,
but it's just a matter of time before I fix it, hopefully with help from someone who has had
similar difficulties with DOS16M.


I never used DOS 6.22 but I used DOS 6 and WFWG 3.11 (with a NETWORK) to share FILES.
