Toshiba Tecra A8-183. BIOS update to version 3.40 fixes this issue.
You must not update from Windows. Modify FreeDOS ISO image and add the unpacked Windows BIOS to it. When starting FreeDOS from CD you should be able to run CHGBIOSA.EXE. Input BIO0046T.COM when asked for the BIOS filename. Works flawlessly.
