This reminds me of a similar problem I had on an older Advent laptop. The problem was due to bad BIOS calls in the firmware. It was fixed by Mr HP Anvin, the maintainer of the ISO boot loader by writing a work around to dodge the wonky BIOS code. http://en.wikipedia.org/wiki/SYSLINUX Maybe you have a similar problem? Does your machine hang with an error message during the boot process?
