I have pasted the controller firmware disassembly here: http://pastebin.com/8frsDCLQ The disassembly claims that the controller supports commands: 01, 05, 06, 08, 0A, 0B, 0C, 0D, 15, 16. I am struggling too much with the 8048 assembly to verify it, but let's suppose it's true. The BIOS disassembly shows the following commands are used: 02 - Restore Drive (?) 04 - Format 08 - Read 0B - Seek 0C - Init Drive (?) The floppy controller ROM disassembly shows that it supports, among others, commands 04, 08 and 0A which would make sense taking into account the above BIOS uses (0A is supposed to mean "write"). So, it appears the controller firmware does not support the command 04 "format". Regards, Michau. Message was sent through the cbm-hackers mailing listReceived on 2014-08-23 14:00:03
