Hi, replaced the factory ribbon cable in my g3 266 desktop with a master/slave (3 females) ribbon cable in order to add other devices, such as another 80 gig HD.

Set the factory 6 gb western digital HD to Master, and the 80 to slave but the 80 gig is not recognized, while the 6 gig is. Tried playing with order of connections on the cable and master/slave jumper settings to no avail.

However, it does get recognized when I put it on its own ribbon cable. (there are 2 ide ribbons going back to motherboard), but had to take out CD rom drive to do this, this is not an option , i need the CD rom drive but still need the extra HD space.

Am I going to have to get a IDE to Firewire enclosure to external it? Hope not.

Help

check your machine to see whether you have a Rev A, Rev B, or Rev C.

Rev A does not support IDE slaves.

Magician has been brainwashed by OWC; there was no Rev C. However, you must have a Rev B ROM to run slave ATA on each of your two channels.

Look it the Apple System Profiler. Rev A has ROM subversion v4.0F2. Rev B has either v4.5F1 or v4.5F2. Rev B ROM can be had and swapped.

hmmm. Actually, I was brainwashed by dookie's brother, Spud, who authored the beige G3 logic board page (http://www.macgurus.com/beta/mbppcg3desk.html) text on the main site, and did all the research. He delved in the TIL and the Developer's site for his data, then synopsized and synthesized in accordance with a gentle format we use for those pages.

looking back at them, there appears to be just two beige G3 revs....as Dookie's text clearly states that rev 3 is in fact the Yosemite logic board.

sigh.

there appear to be two ROM revisions, 40F2 and 45F1, each corresponding to rev A and rev B logic boards. The 45F2 ROM revision corresponds to the Rev C or Rev 3 logic board, which is aka Yosemite.

I think I'm clear on this now.

I looked in apple system profiler 2.4.2 and can't find what you asked.

At any rate, I looked on the motherboard and it says rage II instead of rage pro, which means i'm rev a which means i'm outta luck - so says www.xlr8yourmac.com. (http://www.xlr8yourmac.com.)

Funny thing is, my on site tech support extended warranty company is going to show up at my door with a new motherboard and I hope its a rev b. My mac stopped chiming while trying to do all of this. haha.

I need as much storage as possible with what i'm doing.

thanks,

John T.

p.s. like the commie motif, not that i am one...

that's excellent, John. You know, it is very likely that it will be a rev b board. If it isn't, you could simply point it out to your technician and ask him to come back another time with a rev b. Couldn't hurt to ask. The squeaky wheel generally gets the grease.

oh, yeah. FYI: you just need to look more carefully at the ASP report. The ROM revision is there, as Louie advised.

I don't know where the Yosemite got into this. My info comes straight from Apple's developer pages. My wife's 266 DT (Oct 98) came with a ROM subversion v4.5F2.

The ROM's that OWC were giving away and then selling for $35 were v4.5F1, also Rev B.

Nevertheless, either v4.5F1 of v4.5F2 will allow ATA slaving. These modules can be had, although with more effort and expense than earlier. It's a simple matter to swap.

interesting. According to Apple's Developer docs, ROM 45F2 is also used in Yosemite.

What is OWC and why can't I buy the remedy from macgurus. I've bought from you guys before.

OWC is Other World Computing. The ROM modules are Apple parts and have to come from Apple or scrounged somehow. Be careful, the 4.5F1 and 4.5F2 have the same Apple p/n. not sure about the 4.0F2's p/n, but you have one. Be sure to get one of the first two. OWC was out of them the last I heard. There are some more threads here to search on recent efforts to find one. Try this http://www.sur-tech.com/cgi/page?menu,home .
