It is not possible to determine the setting of the CDROM without removing it from the computer. Meanwhile I read some other posts without a clear solution. One of the suggestions was: An issue with the IDE to SATA adapter. So I ordered a StarTech IDE to SATA adapter (the red one). The adapter...

Next is to check CDROM settings.

Not set a jumper at all is behaving same as "Master", so no improvement but OS 9 is booting.

The IDE to SATA adapter looks similar to that. Jumper seems to be on "Master" position (im am not able to read without removing the adapter from the computer), which is wrong if I read right. After changing the position OS X booted at a similar time, OS 9 did not boot at all but stuck at the...

OS X take some time as well (15s grey + 60s to desktop) but does not show a question mark. There is a SSD instead of a HD build in. How did you solve the conflict?

Yes I installed a new battery before the installation.

Recently I got a Mac G4 Cube with OS 10.3 installed which is working well. Tried to install OS 9 on a second existing partition at the same hard drive from Mac G4 Cube Recovery CD. When starting from that (OS 9) partition it take 25s with a grey screen, then 25s with a Mac with a question...

One of my 475 devices is stable up to 50MHz (assume serial is not working), and crashes at 52MHz. Configuration: 68040RC40 MC88916DW80 70ns internal RAM 60ns RAM module 60ns VRAM 55ns programmable ROM module So you are lucky with 60ns internal RAM. If you are able to compile the extension by...

When you exceed 37/43MHz does the computer crash or show grafik artefacts or just does not run faster?

Next I need to find some place for additional code. As I am operating an LC 475 all code for Wombat boards is not used. This check if board is a Wombat board as jump to the Wombat only routine if yes: 408A014A: SIZEMEMORYPATCH+$014A: MOVE.L $5FFFFFFC,D0 408A0150...

If I am not able to mark internal RAM as bad maybe it is possible to set size to 0. Code below is calculating size of each bank. If memory is found, size and total size is set with 408A027C: SIZEMEMORYPATCH+$027C: OR.B D3,D5 ; 'OR' in 'n' (size of this bank) 408A027E...

Thank you for the hint. So I need to dig a little more into depths. First I rewrote cy384's "ultra wombat hax tool" for MEMCjr in 475. There are only 5 memory blocks accessible by MEMCjr: bank 0 is 4MB onboard RAM (70ns) bank1 and 2 are the 128MB SIMM (60ns) As the SIMM is double sided it...

Within my LC475 there is 70ns onboard RAM and a 60ns RAM SIMM and a programmable ROM module. Due to speed reasons I like to disable the onboard RAM. Prefered solution is changing the code in ROM so the onboard RAM is no longer used. I am quite sure that I found the place in ROM that initialize...

You can figure that out from the pins of MEMCjr. 101 = 4 That one with the white triangle and the via 103 = 3 102 = 2 126 = 1 You may also check that 5 is connected with pin 4 of all onboard RAM chips 6 is connected with pin 34 and 44 of RAM SIMM socket 7 is connected with pin 33 and 45 of...

I ordered this one...
