its weird that it would work on my g3 ibook though, but yeah probably just some incompatibility. shame.

yeah thanks, guess i got caught up in a bit of a red herring and kind of misunderstood what was going on.

theres a chance i'm not understanding something, info seems hard to come by these days on your search engine of choice. ROM revision: $77D-45F6 Boot ROM Version: $0004.18F5 Mac OS ROM file version: 10.2.1 Looks like my boot rom is already 4.1.8? And OS rom is 10.2.1... Is this even the source...

I may be barking up the wrong tree here with the ROM... Im not sure that's the issue. Boot rom version is 4.1.8 but MAC OS rom version is 10.2.1... I'm not sure either of these things is giving me issue. I'm so confused as to whats causing this issue.

Thank you, i need to roll back the firmware on my Pismo because the macos9lives 9.2.2 installer put the 10.2.1 firmware on it and now my firewire doesn't work. So I want to roll it back to 4.1.8, the last pismo firmware.

has its own power.

I need to downgrade the rom/firmware on my powerbook pismo, is there a way to do so?

Dumb Question, perhaps, But how in heck do i downgrade a new world rom?

Alright, looking at it, this rom may be the problem. I'm gonna try downgrading to an earlier rom and see how that goes.

good question, upon checking, ROM revision: $77D-45F6 Boot ROM Version: $0004.18F5 Mac OS ROM file version: 10.2.1

Got a bit of a weird one... Picked up a firewire enclosure to use with my 3.5" IDE MO drive and it works just fine on my iBook G4. Read/write, mount, copy, eject, whatever. But when I plug it into the Pismo, It seems to be sending bizarre commands to the drive. It did this with one of my...

and yeah i was referring to apple HD SC setup. So i'm having a blast with this. I figured out why none of my installers were working, the friend i inherited this system from had overclocked it, which changes the gestalt ID, so the installers couldn't figure out which system it was. So that...

HAH that was the ticket. I have an IDE MO drive, attached to an IDE->SATA adapter, on a USB SATA adapter, plugged into the usb 2.0 cardbus card on my Pismo G4, and i formatted an MO disk with the proper classic mac drivers on it and it's seen for the installer now. I love figuring this stuff...

i know it wont show up on the desktop unformatted, but it wont even show up in the scsi disk tool and it's not prompting about a disk it can't read. I'll see if i can figure out a way to get one formatted on a classic mac system, but i'm not so concerned about it. just want to see if i can do...

I dont remember, but it wont even see the drive at all, no matter how i mess with my scsi jumpers. re: extensions, is there a way i can load third party extensions within liveCD install environment? not that it really matters, but i am now curious.

Yup ive got two of these suckers and a matching hi-fi unit. Got it to boot but i can't get the thing to see my MO drive even when i set it to fixed disk mode. Guess i'm going to have to get a bluescsi finally. Lame. Maybe i'll do what i did before and put a 10krpm server scsi drive in this like...

I got CD boot working! both the yamaha and ricoh CDRW drives were not working, so on a hunch i pulled out my Pioneer DRM-6324x 6 disc scsi cd changer and it worked first shot. Now i'm just trying to find a version of macos that will let me install to the MO drive i have since i don't have a...

yeah the yamaha is the one im trying to boot from. I'll try that 7.6 image, though i had tried the 7.5.3 one also mentioned there with no luck. I think these are the same ones Phipli had mentioned in a previous comment. I'll give it a shot though, since the floppy drive quit working again. This...

Burned that exact image from macOS. My scsi drive of choice is a yamaha CDRW burner. I'll mess with it later I'm done for tonight.

I had cleaned the FDD before, but i tested the floppy detect switch and it was not making contact. cleaned it with alcohol and its now booting off floppies! And i kind of don't want to have to buy anything for this thing. I'm just trying to make what i have around work, and its fun. I have a...
