ROM Rev A has nothing to do with 8 GB limitation, per se, as all "Old World" Macs have the 8 GB limitation for the first partition, for OS X, but not for OS 9. As the IDEs are DMA mode, there is no 128 GB limitation in the chipset, but there is an artificial 128 GB limitation in the drivers (both OS X and OS 9). If you get Intech's Hard Drive SpeedTools, you will get an initializer for OS 9 which can initialize a drive which is larger than 128 GB (actually, it is 131,072 MB). You will still have to have an 8 GB (8192 MB) first partition, if you want to boot OS X. You will then place a partition break at exactly 131,072 MB. The included "white paper" on "safe formatting" will disclose all these details. The "High Cap kext" for OS X will allow that MacOS to access above the 128 GB line. You could install 500 GB drives on that machine, if you wanted to. All the B or C ROMs would do would be to give you Slave support, which is certainly a good reason to install a B or C ROM. The B ROM should fine, as all the C ROM did was correct an error in the support for the video chip which was on the Rev. 2 and 3 motherboards, and the C ROM did nothing for IDE support. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
