Buying a couple STCK1A8LFC for a project I'm doing in my personal time (GIMPS). I'm getting them for $30 a piece and will likely buy many more as the source has nearly 2,000 of them and I can do some creative things with them. I did think about the idea of turning one of these into a DOS machine to play old DOS games on. Not a very demanding application for these. Seems perfect. I can't see any reason why this can't be made to work, can you? Plenty of USB drivers for DOS for instance and I can use a small USB hub with them to increase the ports for a keyboard and mouse. I can partition the storage to something DOS can work with. Seems very do-able!!!
Yes, I know that. Unless disabling UEFI and Secure Boot doesn't work to allow other ways to boot the stick, I'm thinking this is very possible. I saw a video where one of the boot options in the BIOS was Legacy which is encouraging.
Being you're from Intel, you should know what is ultimately possible and what your engineers have tried or have just made impossible to do. Nobody thinks of using this for DOS 99.9% of the time, I'm sure.
I get the two I ordered next Tuesday so I will definitely be testing one of them.
For the purposes of getting DOS or older Windows versions to work, doing this first (except the part about installing Windows 10 which I would never recommend) might be a good intermediate step before disabling UEFI and Secure Boot and switching to Legacy and then attempting to boot from USB:
I always do my testing using the very latest BIOS. Yes, I can select between Ubuntu and Windows (all BIOS offer this choice), but this make absolutely no difference to the issue. I have also played with multiple flash disks, including doing the slow format to ensure I don't hit the compatibility problem caused by some bulk formatting machines used by the flash disk providers.
Have you had any luck booting to DOS? You made me curious so I took a stab at it. I was unable to get my FC stick to ever include the USB device in the boot menu. I tried multiple USB 3.0 and USB 2.0 flash disks. Made no difference. These disks boot just fine on other NUCs and PCs.
