[...] I acquired an old Initio SCSI card (9100) around the time of FreeBSD 4.5. A driver was available from the manufacturer's website for FreeBSD 4.x, so I downloaded this, edited the kernel sources, popped the right bits into the right places in the source tree and it compiled. Great. But of course this was an unmaintained driver. As new releases of FreeBSD 4.x came out, naturally it stopped compiling. However, I was able to hack the kernel sources to get it to build all the way up to somewhere around 4.8 or 4.9. This was great, because it gave me a couple of years of extra life for a very old component. And of course, in the binary-only world of closed-source software this wasn't an option at all and compatibility was not available with new Windows versions. To quote from the Initio website: <quote> ...discontinued products which do not have Windows 2000 or WinXP support. This includes the INI-6100/6102, INI-9100, and INI-9100W adapters. </quote> [http://www.initio.com/support/index-download.htm] So this card simply could not be used with up to date versions of Windows. In the end, the hacking became more and more elaborate and therefore too much trouble, and I just relegated the card to the pile of no-longer-compatible hardware all computer engineers have in their attic. All hardware has an end-of-life, and this has reached it for me. But I _could_ have kept on going and could still be using it in the latest releases. It's up to me, and that's a fantastic freedom that only exists with open source software. By contrast, I maintain a networked Windows machine that controls plasma cutting systems for a manufacturing business. It uses a serial port connection to send cutting patterns to the plasma controller. The serial port communications software was custom-written and runs only on versions of DOS that shipped with Windows up to and including 98. It is specifically incompatible with Win ME and all the NT family including XP and 2000/2003. I don't have access to the source code either of the custom application or any currently maintained version of Windows (of course), so no hacked upgrades are possible and we have to run Win 98 - which is desperately horrible and insecure in a networked environment.
