SV: [syslinux] syslinux tool for Win2k and 'safeboot' option

[Ole Hansen]

Hello Luis

Thansk

Yes we tried that and it works, but if you are in the field and only have
new
clean compact-flash and no DOS, you are in trouble.

I can syslinux directly to the USB card-reader/writer under Linux without
problems too.
It just appears as a SCSI-device(/dev/sda).

best regards
