Ah, now that is an issue I know. The issue is that the filesystem changed a little between System 6 and System 7 - your System 6 is trying to rebuild the structure of the filesystem on the disk formatted for newer OSes, but the disk is locked, so it is failing. For CDs this was an issue with...

It isn't a period issue, this is a BlueSCSI thing. Effectively it is presenting something as a locked disk that isn't a disk, so the OS is seeing something incorrectly formatted, that it can't correct. You can force things to not mount... but this absolutely needs to be sorted from the SD card...

Sounds like there is a/are file/s on the card that it is trying to recognise as an image. Check the log file to see what files it is trying to mount as disk images. If that isn't possible for some reason (I don't have a bluescsi) remove any files you have added other than the disk images you...

That issue is entirely to do with the disk image, not PRAM. PRAM only holds info on which device to boot related to this. I recommend starting from a stock bootable image and working from there. It just sounds like the image is mounting locked for some reason, but that is a bit of a weird...

Yes, confirmed that you need to install 32bit QuickDraw. Little brochure for the card (and its alternative that is identical except that it ships with 1MB pre-soldered). Yours is the 4.8, but upgraded to the 8.24 due to the VRAM SIMMs.

That may be a lack of RAM to be honest. Stuffit isn't the best at throwing actual error messages and tends to just give up and quit.

In the Mode32 control panel itself, then go to the Memory control panel and switch it from 24 to 32bit addressing - you then need to restart. It will forget that setting if you power down without a battery, but will otherwise remember. The only real difference you'll generally notice is that in...

Slimming down to 4MB would be going back to Mac OS 7.0.1 (uses about 1MB with a light install if I remember) or even 6.0.8 (uses hardly anything at all - way less than a MB)... But 4MB is abnormally little for a IIcx, you probably should bump it to around 20MB (4x 1MB SIMMs + 4x 4MB SIMMs) for...

Sad news. Based on the fact that the Performa 630 is a derivative of the LC 475, and its memory controller, the F108 is apparently based on the MEMCjr... plus it uses resistors to set the clock speed as on the LC 475 using a clock generator of the same brand... sounds hopeful... I made a...

Updated version of the Control Strip Module available here : https://macintoshgarden.org/apps/control-strip-475-overclock Most changes (other than the typo I'd made in the menu) are in the background, but this new version seems to be more stable at higher speeds due to refined timings. I've...

I don't have the same card as you, although it is possible to use drivers from other cards. I often use CPU Director by Power Logix with my Sonnet cards. I've found it a little more stable. If your card works without the extension I would just use it like that. But given it crashes with the...

But if the extension already loads before the BeOS loader, then you don't need to make the change. It wont make any difference. Yeah, that sounds like a different issue. I've booted my 9600 with two different G4s, a PowerLogix 350MHz and a Sonnet 400MHz. The only ones I've had trouble with are...

For interest, this is what you get when you use a 466MHz G3 upgrade : ... and this is what you get with a 400MHz G4 upgrade. Note how BeOS 5.0.3 is aware of what a G3 is (PowerPC 750), but doesn't know what to call the G4. It also gets the MHz wrong for the G4 (but right for the G3).

It is probably just visually slow (the SheepShaver window updates at a fixed framerate). Change the setting for the framerate in SheepShaver's settings. Set it to 30 or something (don't go too high or it hogs processor that could be used for computation). If you benchmark it, it shouldn't be...

You shouldn't need a ROM file - it uses the one built into your logic board on a 9500? You seem to be missing a CPU :p The dual processor cards turn up on ebay occasionally for affordable prices once in a while if you keep an eye out. Worth trying to find one if you're using a machine as a...

There are copies of Sheepshaver already compiled for BeOS online, I have it on my PPC BeOS Mac, although its away at the moment. Perhaps try some downloads from here : https://pulkomandy.tk/~beosarchive/index.pl?search=sheepshaver

That is actually something to keep in mind actually - I've found that my Centris 650 wont run at 40MHz if I use my 60ns 128MB SIMMs at all. With other (smaller) SIMMs, I can get 50MHz. It is always worth trying a few different SIMM, although the limit you (JDW) specifically are hitting doesn't...

I'd recommend just desoldering what is there rather than putting faster RAM back. But you still have the risk of melting some of the plastic in the surrounding area. I desoldered the onboard on my Centris / Quadra 610 and on one of my 650s. I probably will on my 475 at some point. I'd like to...

Yes, sorry, I was just trying to explain that there are diminishing returns on the investment of time, I wasn't begrudging it, but there gets a point where the benefits are so small that it isn't worth the time it takes (which would likely be much less time for someone else, but this sort of...
