[one-users] additional parameters for the DISK section

[João Pagaime]

Hello Ruben

got it to work with IDE, with 3 disks (the remaining IDE device is the
cd-rom, and that was the problem: the cd-rom and one of the disks were
both using the hdc hint target

couldn't make it work with SCSI

thanks
João
