Hello guys!
Yes, the 4MB Romy version is functional by Cosmos: http://leblogdecosmos.blogspot.com/2...mo-a4000d.html ...and the new "Ramy" adapter by Cosmos is interesting: http://leblogdecosmos.blogspot.com/2...y-arrivee.html BTW the 4MB version was available (but untested) for a long time now... Thanks to Cosmos! ![]() ![]() Last edited by SpeedGeek; 23 August 2017 at 16:59. |

Serious question: What can one put in a 4MB Kickstart? Does 4MB of ROMable stuff even exist? I've got Poseidon and ROM updates in my Deneb Flash, and it's nowhere near full...

but we lost an enthusiastic member :/ Matt_H: you can add all the c: commands, there is a script to make a module out of them. with an editor for example, booting from floppy, or w/o startup-sequence, can help in some circumstances. i'm sure, once the possibility is given, some creative minds will come up with more usefull stuff. |

Fortunately, the very generous moderating staff here on EAB understands the profound difference between banning a member and banning all discussion of a banned member. Unfortunately, on Amibay the moderating staff was not so generous. ![]() Quote:

If you have more storage space on ROM you can do lots of things!
If this works on A600/A1200 I'm very interested. |

4MB of ROM space would be quite nice for AROS/68k actually.

Very good work by Cosmos (and SpeedGeek).
I still like Cosmos a lot. His work shines above most other hw tinkerers. His blog (even translated by Google) is always a good read. |

I guess a 4MB ROM would just take up space from fast ram if used with a CPU with 24 bit address bus? So why not just load those extra modules into fast ram? Yes, it would need to load them from HDD and it will take a few secs but when would you need that much in ROM before booting from HDD? #8 mentioned AROS but I don't know much about that, except that it sounds like it is a massive resource hog.

With it is possible to put bootdisk to rom. Something like CD32 emulator from IdeFIx package, That would make a nice CD32 setup and also allow CD boot. Possible to setup custom OS3.9 setup with HDInstall tools on ROM? etc |

but maybe after 15 seconds you have a working workbench ![]() it's like the c64, *power on* and you have a working system - now looking for a C2N to plug in ![]() IIRC, the archimedes did it the same way, no boot medium, but could enter it's gui, am I right? this was a cool feature. maybe this is usefull for plasmab and his cd32. #1) speed above when using the debug version! release version of romdisk.device is much faster: boot time to full workbench: 1 second Last edited by emufan; 08 August 2017 at 21:53. |

50ns is quicker than "FAST RAM" as most CPU cards that use 80ns down to 60ns RAM? Or is there something else in the A4000 limiting ROM access to slower speeds? I know there is a jumper on the motherboard for ROM speed. But can that be bypassed all together and force them to runt 50ns? |

Obviously the speed of the ROM is not the limiting factor, or they wouldn't have put the core components of the operating system there.

Romdisk in boot menu and CD32 emulator inside of kickstart. If CD is not presented it boots to very Basic Workbench 3.1.

![]() this way you have a emergency disk, with tools you can choose on ur own. btw. one reason for the "slow" speed is the result of packing/unpacking the content of the disk. #1) it is ultra fast, maybe faster than booting the C64. initially i was using the debug version, now i 'm using the release build of the romdisk.device. now u push reset , one second later you have the workbench ![]() Last edited by emufan; 08 August 2017 at 21:49. |

I had never heard of ROMdisk. It's a great idea.
Can I softkick a modified ROM with MAPROM or does this only work with real ROM chips/emulation? |
