Experience with A9home?

What I meant from my comment above, is that under normal use, using a USB keyboard and Mouse, you don't have do things like unplug them and plug them back into different ports, unlike some PS2 devices.

Really? Do you have a single example? PS/2 ports are assigned specific uses, so in general you can't swap them anyway.

RO 3.5 to 3.7 upgrade procedure

Wed, 10 Mar 2010 16:27:05 GMT

This is correct. As with the previous point, you persist in your Windows-centric view of the world. PC-formatted discs were 640k and 1.44M back in the day, but floppies for RISC OS were always higher-capacity formatted (800k and 1.6M respectively). It's no wonder you can't fit the contents designed for an ADFS floppy onto a Windows-formatted one.

Can an Acorn read a Microsoft DMF format floppy?

Alternately, use an emulator to stick the file into an ADF, and then use something like OmniFlop to write the disk: http://www.shlock.co.uk/Utils/OmniFlop/OmniFlop.htm

RO 3.5 to 3.7 upgrade procedure

I would suggest using something like RedSquirrel/ArcEm/RPCEmu on a different platform and transferring the archives to ADFS-formatted floppies from there.

I would just split the files into two parts on the PC and then join them on the RISC PC. This is a trivial task which I'm sure you don't need us to tell you how to do it.

RO 3.5 to 3.7 upgrade procedure

Wed, 10 Mar 2010 15:37:43 GMT

I now have this OS 3.7 CD to install

No, you've already installed the OS (it was on those ROM chips that you plugged in). This is now the !Boot structure, which is basically just optional advanced configurations on top of the base OS. So, your 3.7 install will work, although you may be missing some handy modules (such as CD support). A pedantic point, maybe, but accuracy is also important.

Two of these files are larger than 1.44. For example, one (file boot2.zip) is 1426 Kb (that actually means (right click - properties) 1459897 bytes. Windows (VISTA and XP) reports error file too large for disk and cannot write file to the disk.

This is correct. As with the previous point, you persist in your Windows-centric view of the world. PC-formatted discs were 640k and 1.44M back in the day, but floppies for RISC OS were always higher-capacity formatted (800k and 1.6M respectively). It's no wonder you can't fit the contents designed for an ADFS floppy onto a Windows-formatted one.

instructions on the CD say explicitlly not to unzip in a machine different than Acorn because extracted files will lose their filetypes and become practicaly unuseable.

This is accurate. Again, Windows and clones use a three-letter period-seperated extension to define filetype (foo.doc, foo.htm, foo.txt, foo.jpg and so on). RISC OS applies hex values to the file itself rather than appending something to the name - so you could rename it to anything, without an extension, and not lose the filetype. However, due to this difference, Windows doesn't know what it's looking at, and will lose the filetype metadata.

I'm not sure if CD support is actually in the 3.7 ROM or solely in the !Boot structure. Have you tried looking at the !Config options since upgrading the ROMs to see if it's possible? Otherwise, I would suggest using something like RedSquirrel/ArcEm/RPCEmu on a different platform and transferring the archives to ADFS-formatted floppies from there.

LCD Monitor Defs for Risc PC

Wed, 10 Mar 2010 14:55:30 GMT

Doh. I forgot about that when making the list. I'll move them down, and remove the 59 and 58 Hz modes (they were there solely to fit in the timings.)

Still, they're worth a shot.

If anyone can try them on an actual RiscPC, and report back, that'd be great.

RO 3.5 to 3.7 upgrade procedure

Wed, 10 Mar 2010 13:47:14 GMT

Ok, maybe in the RISC OS veterans dialect "191-1" is used for years as an equivalent way to say ROM Bank #1 but i do admit that it was not that obvious to me

Back on topic:

the link Blind Moose found helped a lot. ROMS are in place. Booting fine, with 3.7 splash screen.

But the quest is not over.

I now have this OS 3.7 CD to install. In this CD (which i read from my WIN PC, since RISC OS 3.5 does not support CD) there are some (4) files containing the OS 3.7 disk image in .zip format.

So, the idea was to copy from a common PC the zips to floppies and install to RISC PC from FDD. Failed!

Two of these files are larger than 1.44. For example, one (file boot2.zip) is 1426 Kb (that actually means (right click - properties) 1459897 bytes. Windows (VISTA and XP) reports error file too large for disk and cannot write file to the disk.

From Windows, I could extract and re-compress in order to produce zip files of smaller size, but instructions on the CD say explicitlly not to unzip in a machine different than Acorn because extracted files will lose their filetypes and become practicaly unuseable.

So, since i am out of ideas, either:
- you have some
- i do something wrong and can help me fix it
- someone offers himself to receive from me the disk image and re-zip (from his Acorn) the contents into 5 or more disks that really fits 1.44 disk.
- someone already has 3.7 spitted in true <= 1.44 files and offers to send them.

that's it.
again thank you all for your time!

"There's nothing there to indicate 1 or 2."
Apart from the 1 and the 2 third digit from the end!

*cough*

1203, 191-01
1203, 192-01

I'd like a little help about which one goes to bank named ROM1 and which to ROM2.

Judging by what I can see above, I'd take a wild guess if I were you. There's nothing there to indicate 1 or 2.

I guess my sarcasm - as well as my carefully-edited presentation of the numbers - was a bit too subtle
