continue to boot from the internal disk drive, or boot over the network from a boot
server. For more information about booting the Freeway over the network, refer to
Chapter 8.
5.1.6 FreewayOS Daemon Starts
The FreewayOS daemon (fwybsd) is started. This file was specified in the boot parame-
ters as
System_Boot_File_Name.
5.1.7 Initialize and Download ICP Boards
Each ICP board to be downloaded is specified as a separate entry in the bootcfg file. Each
entry contains a protocol download script file (
ppploadb) which in turn points to a spe-
cific protocol executable image (
ppp_2432b.mem). Protogate’s real-time OS for the ICP
(
osp_2432b.mem) is also downloaded into each board along with the protocol image.
While the ICP boards are initialized and downloaded, the version string from each pro-
tocol image is displayed on the serial console.
5.1.8 Enable the Ethernet connection
The Freeway enables the primary Ethernet port and assigns it the IP address that was
placed in the
Freeway_Inet_Address line of the boot parameters. If an IP address was spec-
ified in the
Gateway_Inet_Address line, that address is used as the default gateway router.
5.1.9 Execute Command File: rc.startsra
The Freeway checks for a text file named rc.startsra which is located in the /tmp/boot direc-
tory. If this file exists, the Freeway executes any shell script commands listed in this file.
If the file does not exist, the Freeway continues with the next step in the boot process.
The
rc.startsra file can be used to perform several functions such as:
