[syslinux] inconsistent Int 22h local boot

[Miguel]

I now see that
 Int 22h AX=15h Get feature flags

defines bit 0 as:
  Local boot (AX=0014h) supported

This seems to indicate that this localboot API function is not supported
on some systems.

I am in the process of having this tested on the Dell 1435.

Q: Why is it that a "modern" system would not support this?

Q: Is there an alternate mechanism/workaround for localbooting from the
hard disk?

I suppose I could load in the MBR and fire off the boot process manually,
using AX=0012h, but I was trying to use localboot AX=0014h in order to
avoid having to do that work ...

Q: Is there a library call to boot from disk 0x81?

.OR.

Q: Is there sample code that shows the steps I would need to go through to
do this?


Thanks,
Miguel
