| iBook Clamshell - colour of OS interface | |
| Posted by: AlpineRaven on 2025-09-10 04:34:12 G'day all, I have this iBook Clamshell and I did logicboard swap, I had 466mhz board & DVD drive from very brittle/cracked body - into 366mhz unit. The 366mhz unit is Lime iBook and the Logicboard is from Graphite body. From memory - I knew it'll boot up unique GUI interface to match the body colour ie. Lime iBook will boot with green background interface, blue will be boot into blue... Same what iMacs used to do too. But this one - it'll boot in Blue instead of Lime.... For some stupid reason I recall there is either firmware coding or software to change the colour in the firmware - what was it? Thank you Cheers AP | |

He says that it is tied to a command named "yum" that sends back the color of the computer. | |
| Posted by: chelseayr on 2025-09-12 16:27:25 why am I not surprised it would be aptly named 'yum' as beside it seem like a lot of the non-white g3's were based on some kind of food name colour-wise so yeah "yum me some blueberries please" anyone? heh..don't mind me.. | |

The color is probably stored in NVRAM somewhere. https://forums.macrumors.com/thread...eige-power-macintosh-g3.2303689/post-33883037 Firmware updaters starting with 3.2.4f1 read a byte at 0xFFF04177 which is at offset 0x177 in nvram. h# FFF04177 c@ case 1 of blueberry endof 2 of strawberry endof 3 of grape endof 4 of lime endof 5 of tangerine endof 6 of silver endof grape endcaseOlder firmware updaters (for Macs without config blocks - iMac 233-333 and B&W G3) don't draw using different colors. I don't know if they store a color somewhere in NVRAM. | |
