Disable startup chime on sacrilegious iMac?

[FuturDreamz]

Basically i have an early 2006 iMac (Core Duo T2400) That I have wiped Macintosh from and installed Windows 7.

However, I forgot to disable the startup chime before doing so. This is done in the Mac OS easily, but that doesn't work in Windows. I tried booting the installation disk and muting from there, but that doesn't work.

Does anyone know how I can mute the startup chime, sort of reinstalling Snow Leopard?

Thanks.

Do you mean the windows startup chime, or some kind of mac chime that still works somehow? I would never have guessed that a mac startup sound would carry over. The windows startup sound is relatively easy to disable, if that is what you mean.

It's the Mac one. Basically it's an EFI sucessful boot beep.

You're able to install Windows 7 as the primary operating system on an early iMac? I had no idea you could do this. Interesting.

Only on Intel Macs.

First you have to boot the OS X installer disk, and use disk utility to convert disk to MBR (you can do it in the windows installer, but it's not as easy). then in the Windows installer delete all partitons so it makes the system reserve partition if desired.

it might be possible to boot windows via EFI on 64bit Macs, but it is difficult and if you mess up resetting PRAM doesn't fix it.

You may find that it takes a while to boot, in which case you can run the following command to make the Mac automatically load the BIOS bootloader:

# bless --device /dev/disk0s1 --setBoot --legacy

Run it from Disk Utility on the OSX installer, and if needed make sure you substitute disk0s1 with the partition with the Windows bootloader.

i haven't done this yet, as I haven't had a chance to work on the mac.

turns out the command is

# nvram SystemAudioVolume=" "

and the blessing command does help a little bit, I no longer get that weird icon flashing on the screen for a split second.
