[syslinux] Problems with 4.04-pre14

[Lindgren Daniel]

Hello.

I've been testing pxelinux.0 (4.04-pre14) on some laptops:

- HP EliteBook 6930P with BIOS F.18. 
- HP EliteBook 8440P with BIOS F.06.
- Dell Latitude E4310 with BIOS A06.

When booting pxelinux.0, the machines first display some random letters
in different colors and then reboot.

We've been using 4.02 for some time without problems. I've tested 4.03
too and it seems to work.

Let me know if I should try something. I've tried uncompressing the
files from ZIP again, no difference.

Cheers,
Daniel
