FreeDOS help system (hhstndrd 1.0.8 en)[switches]

Command: switches

SWITCHES adjusts boot time processing behaviour. SWITCHES is a CONFIG.SYS / FDCONFIG.SYS command.


switches=/E[:xxx] /F /K /N /W


/F skips the delay checking for F5/F8 keystroke before processing config.sys [equivalent to SYS CONFIG skipconfigseconds=0] F5 and F8 are only processed if pressed before DOS boots but after the keyboard is set up - right moment is easy to miss. /N disables F5/F8 support [equivalent to kernel config (SYS CONFIG, run SYS CONFIG /? for explanations) skipconfigseconds=-1] F5 (skip config) and F8 (single step config.sys) are ignored. /K forces treating of keyboard as 86 key keyboard, not 102/105 key. Might be useful with BIOSes or drivers which have no or broken handling for 102/105 key keyboards. /E enables moving of EBDA (Extended BIOS Data Area), optionally a size in kilobytes may be specified [xxx, in range of 48-1024] /W is NOT supported in FreeDOS. This option in MS DOS would set a flag for Windows 3.0 to skip loading wina20.386 from the root directory.


SWITCHES is a command internal to kernel.sys and needs no other file in order to work.


IN CONFIG.SYS / FDCONFIG.SYS: switches=/E[:48] /F /K /N /W
