if you have no problems with your laptop atm then leave it alone as a bad bios flash can render your laptop useless and unfixable.

if you must update then do it in pure dos from a floppy or cdr as that has proved far safer than running the flash from within windows.

if you have an old phoenix bios then you will first have to update to A22 before you can update further.

Thanks for your advice. I agree with you. the BIOS is A06 and I think the thing to do is increase my RAM fro 256 to 1 gig.  I was planning on using PC2700 Kinstons memory as that what Best buy sells for 79 dollars. What is your opinion?  And Compliments of the Season to youand your family.

If you do upgrade, I recommend A31 as the best final bios.  A32 introduced a lot of problems.
 
The upgrade path from A06 to A31 isn't the best and there have certainly been problems.  You need to flash from A06 to A22 and this flash must be done from bootable CD or floppy (not from windows!).  At this point you can flash from A22 to A31 (recommended to use floppy or CD but windows should work as well).
 
Common problems include different memory specs for A22 (it won't post with pc2700 ram).  So if you have such ram (which should work for A06) and then flash to A22, you won't be able to POST.  A31 will fix the problem but you have to get pc2100 ram to get there.  Other reports include batteries and AC adapters no longer being accepted as correct -- so again, the required specs may have changed from older to newer 5100 revisions.
 
I would personally advise upgrading.  There are too many instances for pre A20 bioses where the F2 and F12 bios options simply stop working.  If you have a bios password set when this "bug" happens, you are effectively dead in the water if you ever need either menu as a flash becomes impossible at that point.
