Why can't I find an IVT at offset 0x400 of the demo SD card that comes with the Vybrid Tower ?

I'm trying to work out why an SD card I build from scratch (following the Timesys Linux doc) will not boot (no output at all)

According to the Vybrid RM, there should be an IVT located at 0x400 when booting from SD, however the demo SD (which boots fine) does not have this if I examine it using a hex editor (this area is all 0)

Anyone know why /
