+ * How to use the onboard device driver for option rom execution:
-                                                chip drivers/pci/onboard
+ *
-                                                        device pci x.0 on end
+ * 1. You need to add the driver to your mainboard Config.lb:
-                                                        register "rom_address" = "0xfff80000"
+ *
-                                                end
+ *      chip drivers/pci/onboard
-	in your MB mainboard Config.lb
+ *	    device pci x.0 on end
-	2. add 
+ *          register "rom_address" = "0xfff80000"
-		#       48K for SCSI FW or ATI ROM
+ *      end
-		        option ROM_SIZE = 512*1024-48*1024
+ * 2. Reduce the size of your normal (or fallback) image, by adding the
-	in your MB targets Config.lb, afer romimage "normal"
+ *    following lines to your target Config.lb, after romimage "normal"
-	3. create you vgabios.bin under normal bios and put that in dir that targets Config residues.
+ *      # 48K for SCSI FW or ATI ROM
-		# dd if=/dev/mem of=atix.rom skip=1536 count=96
+ *      option ROM_SIZE = 512*1024-48*1024
-	4. after build coreboot.rom
+ * 3. Create your vgabios.bin, for example using awardeco and put it in the
-		# cat ../atix.rom ./normal/coreboot.rom ./fallback/coreboot.rom > coreboot.rom
+ *    directory of your target Config.lb. You can also read an option rom from
-	or use nsxv to build you image
+ *    a running system, but this is unreliable, as some option roms are changed
-		# time ./nsxv s2850
+ *    during execution:
-
+ *      #  dd if=/dev/mem of=atix.rom skip=1536 count=96
-put following in nsxv and put nsxv in your LBROOT
+ * 4. After you built coreboot.rom, attach the option rom to your coreboot
-
+ *    image:
-#!/bin/bash
+ *      # cat ../atix.rom ./normal/coreboot.rom ./fallback/coreboot.rom > coreboot.rom
-MBVENDOR=tyan
+ *
-MBMODEL=$1
+ * Alternatively you can use the following script "nsxv" to build your image
-LBROOT=/home/yhlu/xx/xx
+ * Usage:
-
+ * # ./nsxv s2850
-echo $1
+ *     
-date
+ *     #!/bin/bash
-
+ *     MBVENDOR=tyan
