for OS disk i used file available in file section. Its 3.2 version. DD floppy disk and EMXP on Win XP with internal floppy drive. I used omniflop to format floppy to 720 kb, then again in EMXP for EMAX I format with OS installation.. everything went fine without errors.
When im booting emax from that disk ive got message "bad bank on disk" but i thought maybe its just the OS without the banks on it, thats why i get the message. OS doesnt make any problems with loading presets from other disks or while sampling sound directly to emax ram memory.
