How to get G4 to boot in slave drive (firewire) mode?

Have tried every trick in the book to get my G4 (dual 450, OSX 10.4.9) to boot as a firewire slave drive. (Want it to be a firewire driver for a new Mac Mini.)
Machine refuses to restart in that mode even if I select that startup mode from System Preferences.
Have also tried holding down the "T" key upon reboot. Machine begins to cycle up, then shuts down after about 15 seconds. I am using the keyboard that came with the machine when I attempt this.
Have read that some software (called OPEN OPTIONS) may be installed in Utilities folder. This app can be used to prevent someone from starting the Mac in "T" mode. However, the default is OFF. Further, there's no copy of that software anywhere on the machine. Further, I've done a clean reinstall and booted from that drive but it, too, refuses to boot in slave mode.
Only thing I can figure is the SONNET ATA/133 card is interfering. (Cannot remove it as it enables the 250GB drives I want to share in the first place.)
Any thoughts or ideas?

I would recommend pulling the Sonnet card and testing it. That way, you will KNOW if it is the problem and not just think so. If it isn't the problem, we can help narrow it down. If it is the problem, then we can look for other options to accomplish what you want to do.

Hello! "Tip: FireWire Target Disk Mode works on internal ATA drives only. Target Disk Mode only connects to the master ATA drive on the Ultra ATA bus. It will not connect to Slave ATA, ATAPI or SCSI drives."
I doubt it's going to work except with the master drive on the ide cable of the motherboard.

Thanks, Tom et al.
I'd try pulling the sonnet but I'd like to access the 250GB drive(s) as Firewire. And drives of that size require the Sonnet or the Mac cannot see them.
