I have a problem with my system reload disk.when system re boots,reload screen appears momentarily followed by the error message "Unable to determine BIOS lock. Contact your system manufacturer.I am using a 'Tiny' Power 3500-3 system on windows xp.

I see a few other cases of this error using Tiny recovery CD's.

One idea is to remove the motherboard battery for a few minutes to reset the CMOS.

Another idea is to flash the BIOS but unless you already have a BIOS it may be hard to find as Tiny no longer exists.

An outside possibility is to boot the 6 floppy setup from Microsoft then see if the machine will accept the Tiny CD:

i have had the same problem,if you still have a warrenty phone 08701213195,they will get you a cd to unlock the bios,which tiny has put on.if like me you don't have a warrenty then you will have to try the above ideas or format your disk and start again with wndows xp disk
