I have a copy of Windows XP SP3 Hewlett Packard OEM which i built from various sources. I modified my bios using dmicfg and entered System Manufacurer as 'Hewlett-Packard' as instructed and all is fine. I have an old HP laptop Omnibook xe3-gc which was sold with Win98. In the System Manufacturer is Hewlett-Packard without '. I cannot change with dmicfg as bios are Phoenix. Do you think above copy of XP will work on the laptop? If no, how do i change the System Manufacturer.
