The embedded BIOS on the ZT 5515 is implemented as firmware that resides in the on-board flash
read-only memory (ROM). The BIOS contains standard PC-compatible basic input/output (I/O)
®
services and standard Intel server features.
Support for applicable SBC peripheral devices (SCSI, NIC, video adapters, etc.), that are also
loaded into the SBC flash ROM, will not be specified in this document. Hooks are provided to
support adding BIOS code for these adapters; the binaries must be obtained from the peripheral
device manufacturers and loaded into the appropriate locations.
The ZT 5515 implements two non-volatile memory devices. These devices are listed below and
described in the following topics.
•
Flash: 16 Mbyte Flash Memory device

On-board Flash Memory

The ZT 5515 provides 16 Mbyte of on-board flash memory. The first 1 Mbyte of this memory is
used to hold the system BIOS, and an additional 1 Mbyte stores the secondary system BIOS. The
remaining 14 Mbyte are for customer use and can be used to store an Operating System such as
VxWorks*.
To reprogram the BIOS or update it if it becomes corrupted, use the BIOS Recovery Module and
FLASH.EXE utility available from Intel and discussed later in this chapter.
The flash memory is write-protected through switch SW2-1. See
Write-Protect)" on page 31 for more information.

Flash Utility Program

FLASH.EXE is a utility program that comes with the Intel Development Toolkit. Run
FLASH.EXE to modify the BIOS in the on-board flash memory. FLASH.EXE eliminates the need
for a PROM programmer and for removing boards and chips from the system.
Before attempting to program the flash, make sure that switch SW2-1 is open (see
"SW2-1 (Flash Write-Protect)" on page
To reprogram the BIOS on the ZT 5515, you should do the following:
1. Download the latest BIOS for the ZT 5515 from the Intel website. Normally, the BIOS zip file
also contains the Flash.exe utility you need.
2. Create a DOS 6.2 boot disk and add the BIOS file and flash utility to the disk. Usually other
Windows* boot disks will work fine as well, but use DOS if you run into any problems.
3. Boot the ZT 5515 from the DOS boot disk you just created. You can do this via either a USB
Floppy or off a rear panel ZT 4807. The ZT 4807 provides a standard floppy connector. If your
system does not boot off the floppy you may need to enter the BIOS setup in order to move the
floppy to the first item in the boot order.
