I think I can reply to this - I have a Mitsu MR535U and a DTC 7287 1:1 RLL 
controller.                                                               
                                                                          
My BIOS setup (AMI 386 BIOS) is:              
type 17, cyln 977, heads 5, Wcom 300, Lzone 977, Sec 17, Size 41 MB.      

The DTC ROMS take care of remapping into RLL format when you boot.        
                                                                          
The DTC CMOS on-board configuration (using DEBUG and "g=c800:5") adds:
"CTRL=00" and "SECTOR/TRK=26"
Note there is no size specified in the DTC setup.         
                                                                            
Under DOS 3.30, this gives me 2 partitions of 32Mb and 29.5Mb.              
                                                                          
Any more questions, don't hesitate to ask.
