I don't think so. It gives you three options and if USB boot was disabled, I would think you would not see any options available. Have you tried booting the USB flash drive in all of the USB ports? Did you try the USB-Zip option with Unetbootin? This seems like a EFI BIOS because you can actually boot into Windows first, correct? A standard BIOS would require a password before the computer could boot to Windows. Your best option may be to contact Samsung Support.
Edit: I did find the Syncmaster has XP embedded for an OS. I would not know if the OS was on some kind of hard drive or even if it was placed in firmware on this computer. Have not been able to find any kind of service manual for it either. Many time a search for Syncmaster 730XT leads to just a monitor.
Windows XP Embedded, commonly abbreviated "XPe", is a componentized version of the Professional edition of Windows XP. An original equipment manufacturer is free to choose only the components needed thereby reducing operating system footprint and also reducing attack area as compared with XP Professional. Unlike Windows CE, Microsoft's operating system for portable devices and consumer electronics, XP Embedded provides the full Windows API, and support for the full range of applications and device drivers written for Microsoft Windows. The system requirements state that XPe can run on devices with at least 32 MB Compact Flash, 32 MB RAM and a P-200 microprocessor. XPe was released on November 28, 2001. As of October 2008, the newest release is Windows XP Embedded Service Pack 3.
The devices targeted for XPe have included automatic teller machines, arcade games, slot machines, cash registers, industrial robotics, thin clients, set-top boxes, network attached storage (NAS), time clocks, navigation devices, railroad locomotives, etc.
I was able to find out a little more about this computer. It was sold as a Thin Client which means it's supposed to be used with a server. I don't know what components of XP are installed on the computer but it may be that you would not be able to do much with it. It may not even have a hard drive and XP is embedded on a chip in the computer.
