Since 1994 Dr. Hardware Sysinfo is a synonynom for reliable, precise and uncomplicated computer analysis. Although we released a Windows version in the meanwhile, the Dos version will be developped and used further on. Especially for elementary operations at the machine, like configuration or hardware upgrading but also in the software pre-installation time this tool will be resting your friendly test partner. Technicians will prefer a program like Dr. Hardware Sysinfo, that may be executed directly from a bootable floppy disk; vendors that are confrontated with the naked machine are even forced to use it. Besides this some of the very hardware related features are restricted to the Dos version - for example the EISA slot and the SCSI device analysis as far as a DOS ASPI or CAM driver rather than a WINASPI driver is loaded, detection of L2 cache via short time measuring, VGA retrace measuring or the list of BIOS copyrights. Both the DOS and Windows version keep their high relevance.
