Before using a board with VxWorks, verify that the board runs in the factory configuration by using vendor-supplied ROMs and jumper settings and checking the RS-232 connection.Please note that the pc386, pc486, pcPentium, pcPentium2, pcPentium3, andpcPentium4 BSPs are generic BSPs for generic PC style motherboards.  Forbest results, the board vendor's documentation should be used inconjunction with this document..SS "BOOT PROCESS"When a standard PC-AT computer is powered on, the system BIOS code loads and executes the bootstrap loader. The bootstrap loader is written in 8088 16-bit assembly language. The BIOS obtains the bootstrap loader from the boot sector, which may be in one of several locations: a diskette, a hard disk, or some other alternativessuch as a ROMCARD or TFFS card.  When the BIOS finds the bootstrap loader, it transfers execution to it.  The bootstrap loader finds the bootrom.sys file, loads it into memory, and transfers execution to romInit..SS "TrueFFS support"This BSP supports the optional product TrueFFS for Tornado.  To useTrueFFS, install the product and define INCLUDE_TFFS configurationconstant in the BSP config.h file.TrueFFS is set up to use the M-Systems DiskOnChip 2000 and two PCMCIAslots as a drive for use with dosFs.If you wish to reboot from the DiskOnChip device change the definitions forSYS_WARM_TYPE in config.h from SYS_WARM_FD to SYS_WARM_TFFS..SS "BOOT ROMS"The PC-AT generic boards typically use a boot diskette instead of boot ROMs. The boot diskette includes the boot sector (sector 0) and a DOS file systemcontaining a boot ROM image named `bootrom.sys'.  The boot ROM image could be one of following.  Note, that the Project builds vxWorks_romCompress.bin and vxWorks_romResident.bin.  VxWorks_rom.bin can be built by either Projector the command line.  Other images are built by the command line..TS Eexpand;c c c cc c c cl l l l.

Note that the network interface is not initialized.The boot ROM image must be copied into the floppy disk (a:) or the IDE disk (c:) using the DOS boot utility "mkboot.bat" or the VxWorks boot utilities "mkbootFd" for floppy disks or "mkbootAta" for hard disks. Note to avoid rebooting issues, adjust the SYS_WARM_TYPE parameter appropriately in workspace and propagate the change to yourproject. The default is to use the floppy disk for rebooting.Making boot disks on the host side involves two steps.  Creatingthe bootrom image file and preparing the boot disk.To load VxWorks, and for more information, follow the instructions in the.I "Tornado User's Guide: Getting Started.".SH "Creating a bootrom image"1. Begin by choosing one of the 6 supported boot image types with a .binextension name, vxWorks_rom.bin, vxWorks.st_rom.bin, bootrom.bin, orbootrom_uncmp.bin based on your application needs.  Keep in mind that LowMemory boot images are limited to approximately 640KB in size.    2. Choose an appropriate boot parameters and define them inDEFAULT_BOOT_LINE via Tornado or directly in config.h.  Some examples values for DEFAULT_BOOT_LINE are....CS"fei(0,0)host:/path/name/vxWorks h=90.0.0.3 e=90.0.0.50 u=bob""fd=0,0(0,0)host:/fd0/vxWorks e=90.0.0.50 u=jane o=fei""ata=0,0(0,0)host:/ata0disk0/vxWorks e=90.0.0.50 u=steve o=fei""ata=0,1(0,0)host:/ata0disk1/vxWorks.st".CE3. Compile the boot image by running "make image_name" in the BSPdirectory or see .I "Tornado User's Guide" for instructions on how to compile a bootable image from the Tornado IDE.Preparing a Boot Disk/Diskette.4. The boot loader searches the floppy disk for the file bootrom.sys. Bootfiles with the .bin extension may be renamed to bootrom.sys. All otherboot images require a conversion tool create bootrom.sys. At this point, these instructions fork into three separate sets ofinstructions that apply to Solaris, Windows and vxWorks itself..SS "Creating bootable diskettes from Solaris"Use /usr/bin/fdformat that comes with Solaris. It requires a bootstrap loader file called vxld.bin located inyour Tornado directory tree at $WIND_BASE/host/sun4-solaris2/bin/vxld.binInsert a 1.44MB diskette into the Sun diskette drive, and issue the fdformat command to format the diskette and install the boot block..CSfdformat -U -d -B $WIND_BASE/host/sun4-solaris2/bin/vxld.binFormatting 1.44 MB in /vol/dev/rdiskette0/no_name#0Press return to start formatting floppy.....................................................................fdformat: using "vxld.bin" for MS-DOS boot loader.CEEject and re-insert the diskette.
