(1)  BIG DRIVE:  You can install a hard drive larger than the maximum
size which your PC BIOS supports by adding a 'Dynamic Drive Overlay'. 
This is a DYNAMIC (sic!) BIOS addition which replaces the standard HDD
boot sector. [This limits what else you can install that replaces the
boot sector.]  The hard drive vendors (mostly) supply an OEM'd product
specific to their own drive products for free.  If your new HDD came
with an installation floppy, look for a DDO there (if no floppy, check
the HDD vendor's website); look for 'installation software'.  Ontrack
sells a product for all HDD brands from their website www.ontrack.com.

(2)  PCMCIA:  First choice would be to use the PCMCIA drivers from the
MSDOS/Win3 install disks for the laptop; they would work with DR-DOS. 
Next choice is to use the PCMCIA drivers from IBM PC-DOS 6 or later. 
Also, old PCMCIA modems sometimes include complete DOS PCMCIA drivers.
