Having problem with my Win 98 machine. On boot the system posts a registry\config error, need to run scanreg. When I try to run at c: prompt, I get "the program is too large for memory". I renamed the two files, autoexec.bat and config.sys to free up the memory, but with no luck. I have tested the RAM and is functional, I assume it it the cache memory that I am needing to run the scanreg. From what I have read, I am to the point of reloading the OS, although if anyone has suggestions, it would be appreciated.
