As someone who only runs Linux, I occasionally need to run DOS for updating the BIOS on various machines.

Floppy disks are no more an option, since it has been nearly two decades with machines not shipping with them. Therefore, the only realistic option is using USB flash drives.

One excellent alternative to Microsoft MS-DOS, is FreeDOS, a free clone that needs very little resources to run. It can be used to run legacy applications, and one of them is flashing a new BIOS.

Astrophotography is usually an expensive hobby, and occasionally a very expensive one. But it does not have to be so.

I have been doing astrophotography using used equipment for around 11 months now, with a total of only 7 months experience (if you count the winter hiatus and another two month hiatus in autumn).

While a typical astrophotography setup would cost a minimum of C$2,500 (with the upper limit being as much as 10X that), I have been able to get acceptable results with a total cost of equipment (including a used DSLR camera) is less than C$1,000.
