I'm now wrestling in this problem for days and can't find any clue. The purpose and other details of my intention is posted http://www.wimsbios.com/phpBB2/viewtopic.php?t=8139. The BIOS file I'm working with is Phoenix release 6.0 splitted to *.rom and platform.bin files (not the new *.wph file).
After Phoenix BIOS Editor 2.0.18E extracted the ROM file modules, It always stopped at "analyzing BCPs..." with an error message:
Run-time error '9':
Subscript out of range
I've been searching Phoenix and other sites for many days, but can not find any related article on this error.

HP Omnibook XE2 DB BIOS 2.00 file ftp://ftp.hp.com/pub/softlib/software1/ ... b2k200.exe, please use winimage to extract all.rom file from the disk image.
