I have a Centris 650 that I have been slowly refurbishing over the past few months (yes, that slowly), starting off by recapping all the electrolytics in the PSU, giving the PCB a thorough clean and getting it ready to add 64Mb of RAM, a NUBUS card and, most importantly, replacing the old, broken Quantum HDD with a SCSI2SD. I want to get the system up and running before adding the RAM and NUBUS card.
I have been trawling the 68k forums and t'Interweb for an idiots guide (I'm not a complete idiot, but I like to find something that takes me through the process step by step so that I can follow and understand each stage), and the closest I have found is this: http://www.codesrc.com/mediawiki/index.php?title=HFSFromScratch, which although for Linux has been the best I have been able to find. I notice that many other posts also echo that there is a lack of guidance in setting up a SCSI2SD on a Macintosh, so I don't feel alone! So, following this guide as best I can, I have done the following:
1: I have used SCSI2SD-util to setup the microSD card, and have changed the vendor details following the guidance elsewhere on this forum:
-Set the vendor to the string " SEAGATE" (yes, there is a single space in front of SEAGATE for a total of 8 characters)
-Set the product ID to the string " ST225N" (10 spaces in front for a total of 16 characters)
-Set the revision to the string "1.0 " (with a space after, for a total of 4 characters)
2: Using BasiliskII on a G4 eMac I have created an 800MB system 7.5.5 image which is hosted on the microSD card (following these instructions: http://www.emaculation.com/doku.php/basiliskii_osx_setup).
3: Prepend the Apple Partition Map.... ???? I have no idea what I should be doing here, I have a Raspberry PI with Debian, but despite downloading the package of files relating to HFDISK I have ground to a complete halt. Can anyone give me some guidance? Is there an easier way of doing this in Terminal or similar? What is the obvious thing I am missing?
I have used the patched HD SC app on the Centris (via a Disk Tools floppy), and the computer can detect the SCSI2SD, but wants to initialise the disk (which I am guessing will wipe it), leaving me without my system 7 on board. I've tested the disk using patched HD SC and it has no problems, but I'm assuming that the partition map needs to be updated to become readable.
Somebody, please, help me on this one: I am not an engineer or software designer, I just want to use my old Centris once again!
