How To Build The NeXT ROM Monitor From Sources Release 0.8.30 ROM CRC 0x75cb568c PROM Programmer Checksum 0x40f8 John Seamons 12/01/88

This note describes how to build a binary and S-record file of the NeXT ROM monitor from the golden master source media. Like any other application, you must build on a machine that contains the 0.8 release and the associated include files (in /usr/include).

1. Mount the golden master source media as a Unix filesystem on the machine you'll be building on (have to be superuser to do this).

   mount /dev/od0a /mnt

2. Go to the ROM configuration directory.

   cd /mnt/rom-0.8.30/conf

NOTE: If you just want to build the ROM from sources without altering the basic configuration then skip the next two steps.

3. (optional) Inspect the configuration file "RELEASE" and make any required changes (like enabling certain options or changing the version numbers).

   cd conf

   RELEASE

4. (optional) Configure in the changes you have made.

   config RELEASE

   cd ..

5. Go to the build directory and start a build.

   cd RELEASE

   make clean

   make

6. The "make" should complete without errors. Observe the size of the object file shown. The size under the "dec" column must be <= 65536 to fit in a 27C512 PROM. text data bss dec hex 38840 26588 12 65440 ffa0

7. Build the S-record files for the ROMulator and PROM programmer. The file "mon.srec" is used with the "load" command to download a ROMulator. The file "mon.prom" is an S-record file with shorter (2 byte) address fields required by the Data I/O PROM programmers.

   ../srec/srec mon >mon.srec

   ../srec/srec -2 mon >mon.prom

8. Use your local procedure to download the PROM programmer and burn PROM parts. The Data I/O programmer checksum should indicate 0x40f8 for this release. This checksum should not be confused with the ROM release CRC that the ROM computes and verifies internally at power on time.
