After I succeeded in installing NetBSD on the HP thin client t5710, I wanted to see how well it would work under Microsoft Windows 98 Second Edition (SE).

The biggest problem you run into when trying such an installation is that, in general, you need a floppy disk to boot the Windows 98 SE setup. To perform the installation from a USB stick I followed the steps described in detail in an excellent online article by James MacKenzie. As floppy disk image I used a custom image, instead of the one recommended in the above mentioned article, because I was not able to have the internal IDE flash disk remapped to C:. By using the custom boot floppy disk, I could to use FDISK and FORMAT to partition the IDE flash disk, format it and make it bootable by specifying the /S parameter, that is: FORMAT D: /S. Then I copied the win98 folder to the newly formatted disk, rebooted and started the setup from that folder.
