Make sure the jumper on the Glenside is on the "50" position and make the
modifications into your HDB-DOS LBA ROM to be on that address. Or you can
download and burn into a EPROM the ROM that we used for MiniIDE (link

If everything is working as it should, you will be directed to the Boot
Menu to choose from the starting options. I suggest SIDEKICK that is an
excelent form to browse through the image disks. Here are some photos with
everything working...

That is exactly the intent when we make the MiniIDE in Brazil. A Glenside
type IDE but in a very small form factor. Some MiniIDE photos bellow for
