[syslinux] USB bootable (using syslinux)

[Agostinho Carvalho]

Hello!

I have tried 'raw' and 'bigraw'.
Unfortunately it didn't help.

I also changed to a Win98 image floppy (without RAMDrive support).
It just won't work.

What are the other boot alternatives to MEMDISK?
Maybe a .bss file??

Thank you
Agostinho C.
