They work just fine on all of my DOS machine as long as it floppy drive is connected when the machine is turned on. The BIOS of all machines in this case (2x Dell, 1x Compaq) just presents it as a standard 3.5" floppy drive. Hot swap of course doesn't work, but that hasn't really bothered me at all so far...

Re: [Freedos-user] DOS/16M (was: FreeDOS 1.2 installed on iMac (2011) - success but there are issues)
Yep, that is correct. Due to it, I had to recompile my own OpenWatcom build using a different extender for runtime to continue using it (which is fine). I also continue investigating the root cause of that limitation. Just spoke to rEFInd developer to assess his opinion. Seems that he shares one of the comments from this thread, that there is most likely a limitation of CSM/BIOS implementation in Apple's own EFI implementation of the Legacy mode. But as this is nothing you can't go around with, it's not a show stopper to me to continue testing the environment. To wrap this up I wanted to thank you for identifying the direction for further investigation (keyboard controller with limited BIOS/CSM compatibility on the platform and a bug/trigger in DOS4GW that is generating the crash + error as the final outcome). I'm instantly glad that I've joined the group. Very competent and quick feedback that helped me keep the problem analysis narrow.

Hi Marv, > I'm not sure what driver FreeDOS is using on the Gateway, but if I plug the > floppy into my HP Windows 10 laptop, it says it's a TEAC USB UF1000x USB FreeDOS does not use any USB driver by default, as far as I know. So you probably have USB storage device support in your BIOS and FreeDOS simply enjoys using the BIOS disk :-) In particular after booting from it, or when having it already connected during boot. Note that sizes other than 1.44 MB or low level formatting might not be working in your BIOS USB floppy support, but you can try.

[Freedos-user] USB Floppy
I was under the impression an external USB floppy wouldn't work under FreeDOS 1.3, but I just noticed my installation of FreeDOS 1.3 on a circa 2011 Gateway laptop with an external USB Chuanganzhuo floppy does work. I'm not sure what driver FreeDOS is using on the Gateway, but if I plug the floppy into my HP Windows 10 laptop, it says it's a TEAC USB UF1000x USB device using a default Windows sfloppy.sys driver. It was plug-n-play. I didn't install any drivers on either laptop. I didn't buy this floppy drive for FreeDOS. My main FreeDOS machine has a builtin floppy drive. I bought it to read some old floppies on my HP Windows 10 laptop. -- It's all fun and games until someone divides by zero. ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
