Solved load defaults ( cmos )

October 4, 2016 at 12:09:45
Specs: dos
if i get a checksum error..the cmos loads the defaults . I then have to
press F1 to continue
is there anyway i can get it to boot without pressing ' F1' ie can the 'F1' requirement be bypassed

'press F1 to continue ' or 'DEL to enter bios setup' are the only options presented

thanks

I doubt this is possible. Configuration for such a feature would have to be in the CMOS and if there is a checksum error detected it will not be read because it is unreliable and potentially unsafe. Modification of the BIOS itself is for hard core experts only and even then failure is common.

Try pressing DEL, enter the BIOS, correct the settings that have changed, save & exit.

thanks for the reply
setting the bios is not the problem

the system the motherboard is part of is a no keyboard/no monitor setup
(although they can be connected if need be)

the default settings are fine ..even the default date is of no consequence (1999)
the problem is..it requires 'F1' to be pressed to resume

i need to be able to bi pass this requirement if possible
thanks

The usual cause of a checksum error is a bad CMOS battery. Replace the battery and the checksum error will be solved and no cause to press F1.

thanks for your reply
it has a new cmos battery
the checksum error only appears very occasionally ( for whatever reason )
connecting a keyboard is very inconvenient and it might happen
were there is no keyboard available

so i am still asking ...can the 'F1/DEL' option be bypassed
ie it loads the defaults and boots up

thanks

i am going to accept it is not possible..and make sure a keyboard is part
of the ' tool kit '
cheers

If you changed the battery, the BIOS has reset to defaults. If you haven't pressed DEL, entered the BIOS menu, corrected the settings, & then saved/exit, you will continue to see the message. The other possibilities are that the replacement battery is bad or it was installed upside down. Why did you change the battery in the 1st place?

Sometimes older bios' would have a 'stop on' option for various errors. You could specify which errors are to be ignored and which would halt the boot process.
