[syslinux] Problem entering BIOS - Chison Ultrasound system

[Henry Kubwa]

Hallo sir/madam,

Just to add to my former email I wrote earlier, I have used USB to reboot
this ultrasound unit before and install new files when it crashed before.

The problem we are having now is entering BIOS so as to effect this change,
it is not allowing us, but we can still USB to transfer files so is not a
question of CD/DVD or floppy disk which were used before the year 2000.

Thanks,

Henry.
