Updating bios in ubuntu
I am running Ubuntu 8,04 on a Dell Inspiron 1501Intermittently ... Pretty much all the consumer level stuff uses a dos image of some sort to flash the BIOS. Key ID = 3951B48D As others have advised, you can update your bios with a DOS boot disk if you wish (intructions are on the Dell site). this might be of interest:https://bugs.launchpad.net/ubuntu/ source/linux/ bug/116734 ["PCI: BIOS BUG #81 found" error interrupt usplash] UNQUOTE.When I boot up (or try to), I get two bug messages:1. PCI: BIOS BUG #81  found Sometimes, the booting up process completes anyway; sometimes it doesn't. But the BUG message still appears in the start up sequence screens With no luck I have tried to find a "download" for a Dell/Linux BIOS , so I can update my BIOS : the problem arises in that the available "BIOS downloads" are directed at "Windows Users": I had Windows Vista....chucked it out and loaded Ubuntu in its place. there are no *Anything based BIOS UPDATES from anyone that I've ever seen... And the easiest way to get that is to do what Steve says and get a Free DOS image. I am running an AMD Turion 64x2 on a Dell Pc, but I downlodaded an Ubuntu 8.04, which is a 32 Bit version.Just as this cannot be run under Ubuntu (or any other Linux), .
It is good only as an illustration of a method to make a bootable drive in UEFI as well as BIOS mode.
I use Ubuntu O/S (Linux) with Wolfdale 1333 -D667 R2.0 Asrock board.
I can not get instructions on how to update the BIOS - ALL I get is for windows and DOS. Another problem I have with this board is that USB ports seem to fail occasionally.
If you want a stable portable system, that boots in UEFI mode as well as BIOS/CSM mode, and in 64-bit as well as 32-bit computers, you can try One pendrive for all PC (Intel/AMD) computers.
If you want a pendrive with a live and an installed system, you can try A new and so far successful attempt to create a stable portable system, that works in UEFI and BIOS mode.
