Hm, after digging out my device it is a K1297-1SA01 with Award PowerBIOS 1.00, which boots NT4 from SCSI disk. Guess the plattform is completely different since there is no boot command line, but a graphical BIOS menu.
From BIOS it probes the floppy drive and then jumps to the NT4 loader.
Edit: Just found out it has an AP-1 board. Didn’t know about the additional application processor, which seems to use VxWorks. It has a RJ12 serial port hidden under an “EMI do not remove” sticker, but there is no battery on it.
