Alright, well I made the changes and even put the different NIC drivers in its own folders so it can have its respective protocol.ini files. I used this article for help, How to Create a Ghost 8.0 Network Boot CD. But now, I seem to be running into problems with the USB booting. The CMOS settings are fine, but I now get this message:
Remove disks or other media
Press any key to restart
I used the HP USB Disk Storage Format Tool to copy the MS-DOS startup disk bootsector to my USB flash drive and then I copied over the necessary files for Ghost to boot.
Here's what my USB drive file structure looks like now:
+GHOST (folder)
+NET (folder)
+e100b (NIC folder)
+e1000 (NIC folder)
+b57 (NIC folder)
-netbind.com
-mouse.com
-mouse.ini
-io.sys
-msdos.sys
-command.com
-autoexec.bat
-config.sys
