AMD x2 with older mobo BIOS

This just occured to me as a possible problem.. i bought an asus a8n-e mobo a while ago while dual core's were on the horizon (BIOS version 1001) and didn't consider this prob.

The asus a8n-e needs BIOS version 1005 to run dual core's, and i have 1001.. now to flash upgrade it i need a CPU in there to start with. possible catch 22.

my 64 million dollar Q is this. will my mobo:
(a) accept a dual core as its first cpu (not upgrade from an old one) and only use 1 of the core's until i flash the BIOS.
or (b) just not work at all and refuse to start up.

any views/help welcome 🙂
 
hmm.. i'm still a bit confuzzled..
heard so many people say it will/won't that i dunno the right answer or not 😕
 
how do you know it has 1001? anyway, most boards, like my asus a8v deluxe, will post with a non supported cpu. just put the bios and afudos.exe (which can be found on the asus website) on a formatted floppy. then when you get the cpu:

1. Reset the bios cmos. (Reset the CMOS by switching the jumper only when your rig is powered off or else your BIOS will become dysfunctional). This is to
ensure that the board boots from a floppy first.

2. Most importantly make sure you have only one stick of ram in mobo and make sure that stick is in B1 slot. Third from the left I believe. Check the
motherboard manual for a graphic layout of the motherboard and it will show which slot is B1.

-Start the computer, boot from a bootable floppy, then use another floppy with the new bios and the AFUdos.exe program on it, not ezflash.

-Then type at the A prompt: afudos.exe /(biosfilename).ami

-It will erase, then write your bios.

-Restart and go to bios and configure as you like. You may now put in additional sticks of ram to get dual channel.

this is what works for the a8v deluxe, and pretty sure it will work for the a8n-e.
 
If the BIOS isn't written to support dual cores, the dual core processor will function as a single core processor.
