What exactly does chmod and chown do?
. . . change mode & change owner [of a file]

. . . . I'm at bios 2004. What would be the easiest/safest way to upgrade?
. . what works for me & other cautious geeks is to use a FAT USB stick & to have 2x BIOS' on it.
One is a fallback/rescue known-to-work one [in your case 2004] which you have renamed to 'P5WDH.ROM'
T'other is whichever you want to try, renamed to the short form [8+3].
I suggest the 2403b BIOS, which is available
here . . remember this is 1) a beta, 2) is apparently no longer on the Asus ftp . . but it is a great deal better than the official 2302 'final' IMHO - there are posts about it
here [post 6466 & later]
I renamed this to 'P5W2403B.ROM' & put it on the same USB stick as the rescue ROM.
Boot up with the USB stick in, enter the BIOS, choose 'Tools' then 'Asus EZ Flash' - using the tab & arrow-keys navigate to your USB stick, then select P5W2403B.ROM
Update, reboot, shut down.
Pull the power-cord out, press the start button [to drain any capacitors], take the side off your PC, remove the battery, just above the LH orange EZ-RAID SATA port you will find the 'CLRTC' jumpers.
Move this jumper from L+Centre to Centre+R . . leave there for about 15 seconds or so. Replace to L+Centre.
Replace battery. Plug in, fire up, enter BIOS, reset everything to the correct settings for OSX86. You will need to reset system time & so on.
. . the main advantage of 2403b over 23xx it that the settings to (say) disable or enable Audio will now 'stick' properly - they don't for many folk with the 23xx series.
NB - this above process is by far the safest & easiest way to properly flash a modern Asus mobo.
Never, ever, flash a mobo from Windows
Clearing the BIOS after an update is very important & failing to do so often/usually explains why folks don't see major changes after a firmware update.
NB2: If you completely bork things, booting with [only] the USB stick plugged in will trigger the BIOS to find any file called
P5WDH.ROM
. . . & auto-flash to your rescue firmware.
