OK, who remembers OS 9...? IDE vs. SCSI help needed.

[davec]

On two occasions I had IDE hard drives that would not appear on the desktop when a Mac was booted into OS 9. This occurred even after OS X Disk Utility permitted OS 9 drivers to be installed. One drive was a Samsung (Spin Drive? ) but I can't recall the make of the other drive. Perhaps what I experienced was an isolated incident, but it seemed related to the issues you were experiencing. Good Luck!

Quick and easy solution:

Install 10.4.

Run your OS 9 apps in Classic.

Use VueScan for the scanner.

Might be an OS 9 driver issue, WIth those MDDs you need the version of OS 9 that shipped on the restore media for that computer IIRC. Earlier 9.x disks don't cut it.

Me-
"... it appears to be an OS 9 issue, because, as you say, same symptom from OS 9 CD."
"Issue is w/ OS 9 recognition, and got install from same CD, so thought that might be cause for missing and/or needed extension which is why I asked initially... thought maybe a different install CD/DVD might have better working set of extensions and be explanation for current behavior."

"The only other issue I ever ran into with the DP 1.25 was that it needed its own version of the OS 9 installer discs. I don't think any of the retail discs supported it."

The MDD worked fine in OS 9 when it was new/younger and booted from the internal IDE bus then, from prior drives that were in the machine... I don't recall where the install came from, but would assume that it likely came from the original install/restore discs. It also worked from from a pair of 9GB raided 10K SCSI drives off of probably the same ATTO SCSI card that was just reinstalled to run the drive pulled from the GigE machine. If my google fu is working properly, it appears I'm looking for the PM G4 discs w/ 10.2.1 or 10.2.6 and 9.2.2 to use the latter for the OS 9 MDD install. We have lots of PM G4 discs, and of course I never marked which set went w/ which G4... I'm hoping I was just using the wrong install disc... I have a retail 9.2.1 and a eMac 9.2.2 that were the source from the recent install... must now find and try the MDD discs... Thanks.

Late to the party as usual.

Buzz, try your IDE drives in the MDD on the ATA/66 bus at the front if you haven't already. The ATA/100 bus at the back is the only /100 one in any tower Mac and IIRC may have needed a special driver from the OS install CDs the MDDs came with to be recognized. The ATA/66 bus locations at the front didn't. Again, IIRC.

Let me know if this worked.

I dug out the OEM install discs, and reinstalled 9.2.2 onto the OS X IDE drive, then copied some of the guts of the system folder over to the other IDE drive (both on the ATA/100 bus), and both still have some issues getting fully booted w/ a reasonable assortment of extensions, but they are showing everything now. It boots w/ extensions off, and all drives now show up, but I got as far as creating what I hoped would be a workable set of extensions, but alas, no go. It's running a modded Radeon 9600XT dual DVI, that IIRC, didn't make it into that machine until I made it into a full time OS X'er... I think it was probably running the original Radeon 9000 when I used it as a dual booter... will have to ask Harbourmaster to bring the 9000 back for some testing, unless I can get the extensions under control first. At least some progress is being made, and it appears to be narrowing itself down to some extensions conflicts, and possibly a video card compatibility issue... though I'm assuming that since it work in 9.2.2 w/ extensions off, any video issue is also extension related. During a couple restarts, everything looked OK, but the mouse click wouldn't register; it would move, but not click after it finished booting... I did try opening an icon just as it finished its boot cycle, and it opened the one folder, then stopped working... it's as though whatever the last thing that loaded killed the mouse. Needs more research.

A trick I used was set the clock to display with seconds ticking - you can tell then whether your Mac is actually frozen or if you have some kind of IO extension issue.

Absolutely correct that the MDD's 100Mhz ATA bus is a special extension/driver (it might be embedded in the System file)... so it needs to be installed via the OS install/restore media that came with the MDD because there is NO later release of OS 9 that includes that driver.

I'm racking my brain trying to remember some obscure driver conflicts I remember from OS 9 days... if I recall there was an Apple Audio Driver that didn't play nice with something else that was fairly common in graphic designers' computers back in the day, but only when a 3rd standard apple extension was also present.
