I have a similar situation with my Adaptec 2372B RLL controller.  According to
what I read in the documentation, the controller has its own internal 
drive type table and will automatically set your CMOS when you low level 
format the drive.  In other words, the drive type you see in your CMOS does  
not equate to the drive type of your BIOS but instead to another drive
type table on the controller.  So the bottom line is...DONT CHANGE IT.
  
In response to your other question, if you want to use the 384k of extended
memory as a ram drive, use VDISK which comes as part of DOS.  Reference your
DOS manual for format on the CONFIG.SYS statement that activates the RAM
drive.
