VirtualBox system settings : System Base Memory: 1024 MB Processor(s): 1 Boot Order: CD/DVD-ROM, Hard Disk VT-x/AMD-V: Enabled Nested Paging: Disabled Floppy : Not mounted Though I have not mounted any floppy, a floppy controller exists in the vm.
I tested XP_INST_v02 (which I understand includes firadisk 0.0.1.12) for installing XP SP3 integrated with BTS massstorage driverpack on VirtualBox mapping only once: map --mem /Inst/XP_INST.IMA (fd0) The setup fails in the textmode itself complaining that it could not copy the firadisk files. However mapping twice with map --mem /Inst/XP_INST.IMA (fd0) map --mem /Inst/XP_INST.IMA (fd1) installation is successful! I have confirmed this with wimb's approach given in Post #7 in VirtualBox. I am yet to test this in a real system. Is the necessity of double mapping limited to VirtualBox only? Can redundant mapping cause problems in real hardware?
