This is not exactly a device driver. CTLOAD.COM is a device driver loader from Creative Labs. If you want use a device driver without using CONFIG.SYS (using command line or batch file instead), you can unzip CTLOAD.COM in your path and type "CTLOAD " (no quotes). It worked with HIT-IDE.SYS, SISDR.SYS and (of course) SBIDE.SYS in a Pentium, Win 95 OSR2, using DOSSTART.BAT to load them in MS-DOS mode. CTLOAD can use UMBs, if you use "LOADHIGH" and your system has UMBs. I'd like see any comments about CTLOAD.SYS.
