Germany Lines: 27 Hi citizens of netland! Yes, it is possible to add 3,5 " HD disk drives to the original IBM. I own an IBM XT /w 640 K and a 32 MB hard disk. I added a HD controller of a german firm which holds an EPROM for a BIOS extension. I cannot say wether it will run with older DOS version, for I do use DOS 3.30 (I don't know why anyone should run older versions, by now everything should run under 3.3). It runs pretty well, I have connected to it a 3,5 " 1.44 MB drive and a 5.25 " 1.2 MB AT-like drive. 720 K diskettes are handled with ease. It all runs well, except PC-Tools: It does not recognize that I have installed an HD controller, for it seems that it asks DOS and DOS can't know. (Please refer to my article "DRIVPARM - how do I access it" in comp.sys.ibm.pc and comp.binaries.ibm.pc). If you can't find any american firm selling such a controller, please e-mail me, I'm sure the german firm where I bought my controller will be happy to sell it to you, too. [# disclaimer: No, I don't have any relations to that firm] So long ...
