How to get into the BIOS with a broken keyboard

[xiang2011]

My Acer Laptop Keyboard (an Acer Aspire 5630) has the F1, F2, and esc keys broken. I need to change the boot sequence so I can install an operating system but I can't get into the BIOS to tweak that parameter.



What can I do?



I thought about resetting the CMOS hoping that at the next boot It'll force me into bios to check Acer Laptop Keyboard wrong parameters.



Maybe also flashing a new BIOS (if it's possible from the operating system) could trigger me at the next boot to the BIOS to tweak the boot sequence parameter.



Any ideas on my Acer Laptop Keyboard ?
