IN:
B = total of OZ ROM banks to flash
C = slot number (0 or 1) to blow OZ ROM
IX = points to array space in local Z80 address space of max. 64 OZ ROM banks (1024K).
Each entry has the following format:
-----------------------------------------------------------------------------------
byte 0: byte 1: byte 2:
[first 64 byte sector of file] [bank of first sector] destination bank in slot
OUT:
Success:
Z88 soft reset and return to Index in new, booted OZ.
Failure:
Fc = 1
A = RC_Btl, Batt Low condition
A = RC_NFE, flash chip not found in slot C
A = RC_Wp, Intel Flash is "write-protected" in slot C |
Notes
This is a system call for internal usage by Index, implemented in OZ V4.7 only. This system call is deprecated in OZ V5.0 and future releases. This functionality has been re-implemented as a Shell command, 'updoz', also accessed by Index for <>UPD feature.
This system call updates OZ in slot 0/1, defined via data from "ozupdate.cfg" file and OZ ROM bank files stored in a RAM device. The config file has been parsed for OZ ROM target and bank files by new Index <>UPD command. This system call erases the AMD 512K flash chip, blows the bank files from RAM into the slot, completed by a soft reset.
