Rom Bank 1 has no size constraint, can increase romldr (oversize) without build issue, bank truncation Rom bank 2 usrrom (last app) has size constraint check, shouldnt be function of app Rom bank 2 usr rom pads to end of 32k in its Size, unnecessary as handled by "srec_cat -crop" So * move out the bank size protections (from user rom) into layout.inc * ensre bank 1 has same protection as bank2. * make user rom a realistic size ($200), padding handled by crc check * also good to .ECHO overall sizes of banks, improve logging.

HBIOS Loading Modes:
|
|
ROMBOOT: Startup from ROM Bank BID_BOOT
|
|
APPBOOT: Startup as CP/M application
|
|
IMGBOOT: Startup from RAM Bank BID_USR
|
|
=======================================================================
|
|
|
|
- If not (APPBOOT), include page 0
|
|
|
|
- Base Hardware Init
|
|
- Iff (ROMBOOT), init BBR
|
|
|
|
- Install Proxy
|
|
- Set CURBNK:
|
|
- If ROMBOOT, then BID_BOOT, else BID_USR
|
|
|
|
- Install HBIOS
|
|
- Copy from CURBNK:0 --> BID_BIOS:0 ($8000 bytes)
|
|
|
|
- Transition to HBIOS in BID_BIOS
|
|
|
|
- Copy OS Image to USR Bank
|
|
- If (ROM_MODE), copy BID_OS:0 --> BID_USR:0
|
|
- Else, copy BID_USR:<os image start> --> BID_USR:0
|
|
|
|
- Chain to BID_USR:0
