Tandy 2500 XL ROM DOS Needs Configuration Setup (63915)

This article was previously published under Q63915

Unlike other PCs, the Tandy 2500 XL has MS-DOS in ROM. By default, the Tandy 2500 XL does not read the CONFIG.SYS and AUTOEXEC.BAT file so any changes Microsoft Windows makes to CONFIG.SYS and AUTOEXEC.BAT are not read by the system.

To disable this feature, run the CMOS Setup program for the Tandy and turn on the settings for the "Check for Config.sys" and "Check for Autoexec.bat."

The default for the ROM DOS files and buffers is 10. This can also be changed through the Tandy system Setup program.
