How to reinstall bios at systems ASUS P5W-DH-DELUXE is not open window, I clear the original bios, it that solution? If you speak spanish is better for me because I don,t speak english...

Hey, this is for 60gb win7, 60gb osx and the rest fat32 for data.

once you have your drives partitioned to your preffered choice format the partition you are installing osx to to fat32 from vista (this enables the mac osx installer to see it and format it to mac osx journaled later).

install easybcd 2.0 beta and add an osx boot entry making sure you choose the mbr option not efi.

now follow this guide for installing ahci drivers for win7/vista

Once done reboot your machine and enter the bios (mine is 2801 which isthe newest) and change you settings to the following:-

Now reboot win7/vista and allow it to install the drivers for ahci

Now that all of the preparation is out of the way it's time to chuck in the ipc osx dvd and install:-

Once the dvd has booted choose disk utilities from one of the drop down menus and format your fat 32 partition from earlier to mac osx journaled then exit disk utilities.

now click continue and choose your destination partition and choose customize

do not choose any kernels as it will install vanilla by default

for video drivers choose whichever best fits your card (highlighting each one should tell you what they are for. if this doesn't work it is possible to reinstall and choose no card and install after

For my card i settled for a post install of the nvidia version 2 drivers and nvdarwin.kext and it is running at 512mb instead of 1024mb. This is ample for now and as Apple are now using these cards it won't be long before the one click 1gb driver will be available (i hope).

the chipset drivers you need are ichx sata drivers and the jmicron driver (there are two, it's the top one you want)

for sound select alc882 and under legacy drivers also choose alc882 address 0 (the sound might not work on first boot but if you reboot and go into system preferences/sound/output and change to internal speakers it will be fine)

ethernet drivers needed are the marvell yukon ones and the wifi is realtek rtl8187/l

choose the patched usb drivers (top of the 2 options)

choose ps2 keyboard fix

choose apple smbios patch and select whichever one fits your ram

Double check everything and then install and find something to do for half an hour.

Have you reinstalled the BIOS or windows?
To clean the BIOS, take the CMOS battery out for 1min and put it back.

Let me know if you need further assistance
