How2 program a ROM through the serial port.

Caution there are two procedures below....
Be sure you are using the correct one. 
We use 2.10.1.rom as an example image file, use the correct one!

Make sure there is no chance of power failure on the RaQ
If this procedure fails, (once erase starts) the ROM must be replaced!!!

Note: RaQ3/4/XTR Servers use 1M ROMS.
 
 THIS PROCEDURE ONLY WORKS ON 'AMD' ROMS (AM29F080B)
 CHECK YOUR ROM BEFORE ATTEMPTING TO REFLASH

============ D I S C L A I M E R ========================
Use / misuse of this procedure is not our responsibility
=========================================================

Ues a PC running Linux (no x-windows please)
 to switch sessions use 'Alt + Fx' example Alt+F1 Alt+F2
 best to be 'root' on the 2nd session

connect to the console port on the RaQ.
Start a minicom session on the PC
  115.2Kb, 8 data bits, 1 stop bit, no parity, no handshake
Open a second terminal session on the PC
  cd to the directory containing the ROM image. (Be prepared step)
Switch back to minicom session

Get the RaQ into ROM menu mode.
=========================================================
If the Current ROM is 2.2.x or 2.3.x or 2.8.x (RaQ3/4/XTR ROMS)
=========================================================
In the minicom session;
 execute;
  > boot
  > dl_kernel
  Switch to second terminal session on the PC.
   execute; (use the correct rom, example 2.10.1.rom)
     cat 2.10.1.rom > /dev/ttyS0 (S0=Com1 S1 for Com2)
   Switch back to minicom session
   wait for download to complete
     Should read "done"
   execute;
    > main
   execute;
    > eeprom
   execute; *CRITICAL DO NOT INTERRUPT*
    > write_eeprom 0   (note: that is a numeral Zero)
   wait for process to complete 
   wait a few seconds then;
   Power cycle the RaQ

===========================================================
If the Current ROM is 2.9.34 or greater (RaQ550 types)
===========================================================
  In the minicom session...
  execute;
    > eeprom
  execute;
    > write_eeprom
  Switch to second terminal session on the PC
    execute;  (use the correct rom, example 2.10.1.rom)
     cat 2.10.1.rom > /dev/ttyS0 (S0=Com1 S1 for Com2)
    Switch back to the minicom session
  *CRITICAL DO NOT INTERRUPT* once the actual erase starts...
  Wait for reflash to complete
  wait a few seconds then;
  Power cycle the RaQ
