[syslinux] Strange Lockup

[B Royles]

Hi All,

We seem to have a strange problem with our NEC ML4 pcs.

When using pxelinux to network boot, we are getting our menu (using menu.c32) when we choose a option the machine just locks up.
If the option requires a password it shows the password box , I put in the password and then it locks up. But strangely the machine will boot from local disk which is an option on the boot menu.

Our config files are at the bottom of this mail.

Any help is appreciated. Or if you need any more info please let me know

Thanks,
