I'm still not sure we know what TRT is. Although the MB/64hd/32sect >sounds like the best bet to me. No, it gratuitously breaks booting with kernels above 1GB. If you leave the partition table empty or put only invalid entries in it, then some BIOSes (ncr) will DTRT and invent a geometry with <= 1024 cylinders if possible. >2.

The NCR BIOS accepts anything reasonable. It's going in the other direction that is the problem - you can easily create configurations that work with NCR but aren't portable. Bruce
