Hello, I am having a problem booting into OS X 10.2 with my biege g3 which is now a biege g4 (XLR8 G4 450). Here is the problem: My computer works fine in 9.2.2 but will not boot into os X with both my ATI RADEON MAC EDITION **AND** my Sonnet Tempo Trio Card installed. I can boot into os x 10.2.8 with no problems if i use just the ati mac editon with the sonnet tempo trio pulled out of my system. Or vice versa. I cannot boot with both! The computer hangs without the mac os x startup screen or in single user mode the machine locks when looking for the hard drive. I have zapped my pram, slowed down the processor, switched pci slots, ran norton disk doctor, and updated the ati mac editions firmware and the sonnet tempo trio's firmware. PLEASE HELP WITH ANY IDEAS!! THANKS!! My system specs: Mac Biege G3 minitower 768MB PC133 SDRAM 450MHZ XLR8 G4 Upgrade @ 534MHZ System Bus @ 66MHZ 120 GB MAXTOR 7200RPM 8 GB BUFFER HARD DRIVE 12X HP CD WRITER ATI MAC EDITION VIDEO CARD 32MB VIDEO RAM SONNET TEMPO TRIO |

From looking at the mac roms, "fcode-debug?" doesn't appear to do anything in Open Firmware 1.0.5 (8600 etc) or 2.0f1 (Beige G3) and maybe other versions. I might be wrong about that (like I was about pci-probe-list in Beige G3s - I couldn't find the usage because the Beige G3 doesn't refer to pci-probe-list by name, unlike the 8600 which does). If "fcode-debug?" actually did anything then the default value of "false" would be the value that would save some RAM by not keeping names of tokens defined with the "headers" command. ATI cards and the Sonnet Trio card both do not use "headers" so "fcode- debug?" wouldn't change anything. The Adaptec 29160N has tons of "headers". That would be a good card to test if "fcode-debug?" works. Everything defined in Open Firmware is added to the Open Firmware dictionary which starts almost 3k before "rmyself!" (I don't know how to get the exact starting address) and ends at the value of "here". To get the number of bytes used in the dictionary try this Open Firmware command here ' rmyself! - .d On my 8600 with Sonnet Trio and Radeon, the number of bytes is 654248 or 639k (+ 3k = 642k). The ATI firmware doesn't use compression. A Radeon 7000 takes about 145k of dictionary space. The Radeon Mac Edition takes less. The Sonnet Trio has a 64k ROM with 5k of FCode firmware that uncompresses 59k of encoded data in the firmware to 92k of FCode in the dictionary. The Trio takes about 258k in the dictionary after the FCode is compiled and the device properties are created. |

After fcode debug? true.......you did "reset-all" command. Leave auto-boot? false so you'll get the OF screen, reinstall the radeon and or Sonnet Trio and see if you get the OF screen if not fcode debug? true can't fix this and I don't know what else you could do. |

I successfuly turned the debug to true but now i can't get a startup screen in osx (white screen with apple) or any text in single user mode. OS 9 boots fine. I think my mac is cursed or wants to be retired. If you have any other ideas please let me know! Thanks! |

Sorry, "setenv fcode debug? true" for got the ? If you reset the PRAM or use XPF after setting fcode debug to true it will reset back to false."printenv" is the command to see your env settings. |

LYONSDJ88, I am not experienced in using open firmware. I tried your command "setenv fcode debug true" which gave me an "invaid config name." any more insight or helpful tips for open firmware would be appreciated. :) |

If you know how to get into Open FirmWare try Fcode Debug? true. Sounds like the trouble you are having is both the Sonnet Trio and the Radeon use compression in the FirmWare Fcode drivers. You run out of Ram for Open Firmware to use for exe. the Fcode. Setting Fcode Debug? to True should free up more Ram and you should be able to Boot OS X............................................. setenv fcode debug true........................................................ I think that is the command. |

Does it matter if you have Rev C or not? Too many cards vying for limited 4MB of boot RAM. Does it happen if you use a G3 instead of G4, too? I think this is a known problem. Came up with Vintage (pre-Beige G3) trying to use Sonnet Trio and Sonnet G4/800s. |
