I removed the network ROM from the front slot and the network module from the side slot. Still, the machine doesn't boot from Carnivore2 and doesn't allow any other devices to boot either. I will go through the bus signals with my oscilloscope during the weekend.

This machine doesn't have any CP/M, Painter and other stuff. That's why I was quite surprised when Carnivore2 stopped working with it. I even tested it with Toshiba HX-10 in the 3rd (back) slot and the cartridge could fully use that slot. In the next version of the Boot Menu slot 3 usage can be configured.

Okay, could it also be a power supply issue?

About the next release, do you think the C2 could hold WAIT signal during FPGA initialization? That way BIOS will only start if device is ready. And then would it be possible to configure the boot menu to be disabled and C2 generally boots default config without extra reboot (boot menu could still be invoked by pressing a key, e.g. UP cursor)? It would make everyday life with C2 with Nextor easier imho. And of course I am saying this should be optional for those who wish it the current way of working would still be possible.

The next Boot Menu will have configurable autostart delay. If you set the default configuration entry for autostart and put 0 to the delay variable in the configuration screen, your system will boot faster.

The dual-reset feature is on by default, but if your computer starts after Altera chip gets initialized (~200ms), you can disable this feature to boot faster. We don't plan to hold the WAIT signal as this requires the modification of the board.

Hi!
I bought a new Carnivore2 from 8bits last autumn and now I finally got time to try it out (long story). Anyhow, I'm trying to flash rom files but run into some troubles. I start the DEF-config and go to the folder where I've stored my rom-files. When I write "c2man" I get "Unrecognized command" and "c2man filname.rom /a" gives the same answer. I'm able to open c2man in the c2/cr2 folder, but not elsewhere. Is there some new short command in the new version?

Sorry to bother. I think I solved the previous mentioned problem. I don't know why it occured, maybe something went wrong when copying Autoexec.bat during the first dump on the CF-card.
However, everything got back to normal after I reinstalled some of the files on the CF-card, including the Autoexec.bat.
Maybe Windwos somehow skipped the file earlier... not sure. Thanks anyway Wink
