[My apologies if this is a repeat post; I didn't see this in the digest.]
Greetings, To make a long story short, I was trying to install YDL on a PowerMac G5 hard drive, with the intent of swapping the drive into a headless G5 Xserve of the same vintage. I installed YDL just fine, but I could not get the PowerMac to boot up headless. Eventually, I tried this: nvsetenv boot-screen enet:0 [ENTER] nvsetenv console-screen enet:0 [ENTER] nvsetenv input-device enet:0 [ENTER] nvsetenv output-device enet:0 [ENTER] (from http://us.fixstars.com/products/y-hpc/userguide/netboot.shtml) As you might guess, this did not fix the headless boot issue. Now the PowerMac turns on but eventually the fans spin up and there is no output to the screen. It responds to ping and gets an ip address, so it is talking to the dhcp server. I believe it is still set to boot from the hard disk, nvsetenv boot-device hd:,\\:yaboot so I don't think a netboot is possible. But please correct me if I am wrong. Is it possible to send open firmware commands via tftp at this stage, or somehow reset the nvram settings? I have tried holding down the power button until the long beep. I have also removed the internal battery. Unfortunately, these units don't have serial ports (unlike the Xserve G5), so I cannot open a serial console. I gather from extensive googling that booting headless is not possible in this case. Or maybe there is a non-public proprietary yaboot patch somewhere. Any suggestions would be appreciated. Fortunately, the G5's original disk is intact and fully backed up, but it would be a shame to lose this little puppy. -Ed ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Edward D.
