I want to create an OS 3.9 Boot floppy to install 3.1

Try this version of SFS: http://www.xs4all.nl/~hjohn/SFS184.lha
or this version of FFS: http://aminet.net/package/disk/misc/ffstd64

Both should work with an 8 GB drive without further patches.

To make the OS 3.9 FFS or the current version of SFS work with harddrive bigger than 4 GB you need to extract the newer scsi.device from the AmigaOS ROM update or take the one from BB3 or BB4. It needs to be loaded from startup-sequence and causes a reboot on every cold start. It also implies that the boot partition is smaller than 4 GB. With the older versions I linked above you can make one bootable 8 GB partition which covers the entire CF card and they don't need to reboot on startup.

:pint:

Does PFS3 require a newer scsi.device or any additional files or patches for HDD's larger than 4GB, or to have an 8GB or a 16GB CF card as one partition which covers the entire CF card? :confused:

If you use PFS3ds (the direct-SCSI version of PFS3) you can use up to 8 GB on the internal IDE bus without additional software. For the 16 GB drive you need a new scsi.device.
