=============================================
How to assemble and link modified Bios-Files:
=============================================

Modify the standard Bios Files:

AUTODPB1.ASM
TVI950.ASM
USRDEF1.ASM
USRROUT.ASM


Urgent link Example:
--------------------

A>SUBMIT BNKBIOS

--->

link bnkbios3 [b] = bioskrn1, time1, boot1, autodpb1, ramdisk1, autodsk1,
                    tvi950, chario1, scb, usrdef1, rgbterm1, usrrout,...

Thus the linker produces a new system page relocatble  BNKBIOS3.SPR-File 
ready for use under GENCPM.

Important Note: 
---------------

The  Code-Section  of the BNKBIOS3.SPR File (CSEG) must not  exceed  1.5 
kByte  to  get  a TPA of 60 kByte.  The CSEG region printed out  by  the 
linker  should  be within the region of 0500 - 05FFh.  If not  you  must 
adapt  under system 8030/43 the label 'TPALEN' in the USRDEF0.ASM  file. 
Under system 8010/23 you can lower the TPA without troubles up to 0C0h.

The linker message should appear as follows (if not otherwise defined in 
TPALEN) :
                   ----

ABSOLUTE        0000
CODE SIZE       05XX  (0000 - 05XX)
DATA SIZE       ...   (0600 - XXXX)
COMMON SIZE     0000



Then  run  GENCPM  to create a new CPM3.SYS File using the  input  files 
RESBDOS3.SPR, BNKBDOS3.SPR and BNKBIOS3.SPR !




                HOW TO CREATE A NEW CPMLDR:
                ==========================

The  CPMLDR  is  a  simple non-banked CP/M System  how  resides  on  the 
reserved  system tracks of your system-disk.  Its purpose is to load the 
file  CPM3C(E).SYS  from the data-tracks of  the  system-disk,  put  the 
banked  portions  of CPM3C(E).SYS in banked memory and to put  the  non-
banked  portions  in common memory.  The CPMLDR consists of  two  parts: 
First part is the CPMLDR-BDOS how controls the second part,  the CPMLDR-
BIOS.   The   CPMLDR-BDOS  is  supported  from  Digital  Research  as  a 
relocatable File named CPMLDR.REL . The BIOS-Portion is also relocatable 
and  consists  of two parts LDRBIOS1.REL  and  LDRDPB1.REL.  The  module 
LDRDPB1.REL  is user definable similar to the AUTODPB1.REL-File.  If you 
install  a new diskformat you must redefine the file LDRDPB1.ASM in  the 
same manner as AUTODPB1.ASM to create a new LDRDPB1.REL file.

Assemble the modified file LDRDPB1.ASM using RMAC:

A>RMAC LDRDPB1.ASM

Then link the new file with the two other loader modules using LINK:

A>SUBMIT LDRBIOS1

---->

link cpmldr1.400 [l4000] = cpmldr, ldrbios1, ldrdpb1

Note the load adress of the CPMLDR1-File is always 4000h. At this adress 
the Bootloader places the CPM-Loader and starts it. After creating a new 
CPMLDR  put  it  onto the system tracks of your new  system  disk  using 
COPYSYSN:

A>COPYSYSN CPMLDR1.400
