Hi, I am using a pretty old ROM-simulator which is connected to the pc at the parallel port. Now I updated to Windows XP :-( Is there any idea how I can still use such a device under XP? Thank you ...Leo
Yes, there is. There are special drivers that can grant a process direct access to the I/O ports. GIVEIO.SYS is the original idea, other, similar ones exist. To keep this marginally safe, you'll still need access to the source code of the program, though --- otherwise, you'ld have to open I/O ports access for all programs on the box, and that's a rather sure path to desaster. Or simply don't use XP. Keep your DOS.
"Or simply don't use XP. Keep your DOS." Any scrap PC these days will run DOS - surely you can find an old one for this? Or you can get a Mini-ITX motherboard for under sevety quid - why not make yourself a DOS box (literally!) for your old crock hardware?! http://www.mini-itx.com/store/default.asp?c=2
Thank you, for all replies. I will check the giveio.sys. ...Leo
