[QUOTE="dhoggan, post: 1840036, member: 403743"] Hi, I'm hoping this is the right forum, but apologies if not. I have a Mac SE with a Superdrive (and relevant chipset) that can successfully read and write 1.4Mb floppies. It also has a SCSI2SD setup with two virtual devices - a 2GB device 0 (for OS) and a 12.something GB device 1 (for data). The OS partition was a disk image downloaded from savagetaylor.com - the 2GB base 7.5.5 image - and this allows the Mac to boot and is usable. I've installed some Infocom adventures a and After Dark v2. The issue I have is that I want to complete the OS installation but have tied myself up in knots trying to understand how. I have downloaded the 19 part v7.5.3 images set off the internet archive, and on my iMac G5 (running Leopard) I can extract it as a mountable disk. Not what I want, but it suggests the images are not corrupt. I've copied each of these files to the SE but when I click on the SMI (aka part 1) it gives an error saying it cannot be opened because of error type -199. I'm obviously not understanding what I am meant to be doing, but how can convert the 19 part 7.5.3 set into floppies that I can use. My aim is to either expand the base installation of 7.5.5 that I have to a full version, or create a set of floppies that I can then use to erase device 0 completely and install a fresh copy of 7.5.3 - which can then be upgraded to 7.5.5. Any help really appreciated! Thanks, Dave [/QUOTE]
