The ZT 5524 / MPCBL5524 provides 16 MB of on-board flash memory containing the system
BIOS.
The flash device is divided into eight pages mapped into a window in extended memory
(FFF80000h–FFFFFFFFh). The BIOS occupies 512 KByte in flash page 0. To reprogram the BIOS
or update it if it becomes corrupted, use the BIOS Recovery Module and FLASH.EXE utility.
BIOS Recovery Module
The ZT 5524 / MPCBL5524 provides a 512 KByte EPROM programmed with a backup copy of
the BIOS. If the ZT 5524 / MPCBL5524 system BIOS stored in on-board flash becomes corrupted,
the ZT 5524 / MPCBL5524 can boot from this BIOS Recovery module and flash memory can be
reprogrammed via the FLASH.EXE program.
The board is shipped with the BIOS Recovery module installed in a 32-pin socket (U9). If the
EPROM is removed for any reason, ensure that it is correctly oriented when reinstalled. Orient the
beveled corner of the BIOS Recovery module as shown in the “BIOS Recovery Socket Location”
figure below.
