Upgrade 386 PC to UN*X

[Orville Weyrich]

I have a 16-MHz 80386-based AT-clone (Goldstar Technology GST-386) which
is built around a Micronics motherboard and which has an Adaptec 2372 RLL 
controller, Seagate ST-4096 hard drive, 1.2 Meg floppy, 8087 coprocessor,
two standard RS-232 ports, two standard parallel ports, a CGA video board,
2-Meg of main memory, and AWARD BIOS version C3.03.  I am currently running
MS-DOS 3.30 and am using TURBO-Pascal type applications.  I only want a
one- or two-user system.

QUESTION # 1:  Has anyone brought up some flavor of UN*X on any or all of the
hardware described above?  Any recommendations?  [I realize that I may need
more memory -- but how much?]

QUESTION # 2:  How heavily does UN*X utilize the PC BIOS?  I had trouble
getting my hard disk to function reliably using Phoenix BIOS, and am
concerned about how UN*X will handle my disk/controller configuration.

QUESTION # 3:  I still need to use this box for MS-DOS applications.
Eventually I would like to migrate my applications to UN*X, and so would
like to be able to run TURBO Pascal and applications implemented in TURBO
Pascal under UN*X with the ability to have the applications under MS-DOS
communicate with processes running under UN*X.  Some of my TP applications 
use LIM EMS.  Any recommendations?

QUESTION # 4: Alternatively, how hard is it to have both UN*X and MS-DOS
to reside on the hard disk and choose one or the other when booting?

QUESTION # 5: Finally, I am considering upgrading my CGA card to a
Paradise VGA-Professional.  Will this mess up UN*X?

Any help is appreciated.

Thanks,

ORWJr.
