Firstly I'm not one of the developers but just one of the OS4 Beta testers like Darren and Karlos
OK, understood, but you'd obviously got the interest, that Hyperion lost after they released Classic OS4.0, and still have, which is good for us all, so big thanks to you, and the others who pursued the idea like you.
There are lots of things as an Amiga user I'd like to see supported in the Mediator. But thats down to the development team.
Is the DMA 'hack' driver possible to re-write so that it would be Classic OS4.1 legal?
I've sent messages to Elbox about the DMA pronlem with the Mediator, but had no response, but then, I know that they are on the betatesters list so surely they can be approached directly by yourselves to get them to implement it, if it is possible to do so, as it's a feature definitely worth having. I believe the code is in ASM at the moment, but I would have hoped they still know how it works, and change the code to system legal code to re-implement it, if it's possible to do so.
At this time on the A1200 USB is limited to:-
Desktop PPC A1200 (No Expansion Bus) - Subway on Clockport / Poseidon 4.4
Tower PPC A1200 Zorro2 - Deneb in Zorro2 slot / Poseidon 4.4
A native Deneb driver was mentioned in the press release but this would only be benifical to PPC Amigas with Zorro slots.
The Subway card would cause me to remove my HyperCOM parallel/serial card that I use extensively, unless a 4 way clockport add-on card is supported under Classic OS4.1, so I need to know if a 4-way clockport card has been successfully betatested during development?
I take it we are basically talking about the Micronik A1200 Zorro board for using a DENEB card in an A1200, is that correct? If so, that board does not support PCI slots so you'd lose out on PCI hardware, in particular the GFX card enhancement which I consider is a major feature of Classic OS4.1, wouldn't you agree? If so, that Zorro option, for me, would have to be avoided to allow the access for the more important PCI slots in the Mediator.
I have a Mediator TX, so do you have that model, 6 PCI slots?
It would require implementing Elbox's DMA Hack into the kernel as PCI EHCI cards require DMA and don't work in PIO mode AFAIK.
I think you are correct there, from the little I know, and have been told. The DMA 'hack' would be really beneficial as it would allow lots of other cards to be added back to the Mediator slots in due course, but as far as I know Hyperion are dead against it, unless you and the other betatesters feel it should be supported, I know I do already, but if you can also convince Hyperion of its worthiness.
Yes in various config I also move my ppc to the Z2 machine when needed. See Sig :-)
Seen it, and glad you have a few assorted setups. I offered my services for the betatesting, but was not 'honoured' with being able to help out.

Hundreds and Hundreds. I had the job of creating the installer and putting the iso together.
It was made on an A1200
I didn't know that, I got the distinct feeling that it was created on an A4000, as the A4000 seems to be more enhanced for Classic OS4.1, but that's a pleasant surprise.
The install is a breeze.
Firstly the bootfloppy load residents a new 68K scsi.device and then mounts CDfilesystem and then boots the OS4.1 kickstart modules off the CD.
The Amiga then soft reset and is running on the PPC as with OS4.0.
So is the FastATA device automatically found and used as a native scsi/ide device?
If you have replaced your floppy drive with a HxC2000 floppy emulator don't worry because there is an adf of the boot floppy on the CD to use with those SDCard based emulators.
I've not, but wasn't aware that feature existed, so thanks for that nugget.

If you have removed your floppy you can boot into 3.x and start the install from there.
A lot of work has gone into the installer as it support AGA, Zorro and PCI solutions.
If your running on a mediator with a pci voodoo / Radeon the installer will open on 1024x768.
Zorro2 installer opens on a 800x600 screen for legacy z2 cards.
AGA opens on a PAL or NTSC screen depending on your base 1200.
I wasn't aware of all that. Is all this mentioned in the OS4.1 Installation booklet?
What other info is in the booklet?
Classic OS4.0 Quick Installation guide did not give enough info to people coming into OS4.0 'cold' like I was, as kicklayouts, etc are all new, and I for one would like to know what goes where, and what affects what.
The OS4.0 Quick Installation booklet didn't give any details about the different colour error screens, nor has it since to my satisfaction, so are you in a position to give some insight into that part of the OS?
Is the 'S' directory still used, and are the kicklayout files in there, and are they editable, and what precautions are there if you mess up editing it, and can you start Classic OS4.1 with just a shell prompt, or is it far too complex to do that?
My OS4.0 got so messed up, that I never got back into it or the OS itself loaded after one successful boot into an AGA bootscreen, and then I changed it for Picasso RTG and then I just got constant reboot/error screen, and so gave up, it was all messed up, so even after 4 years of waiting for this upgrade I am still a novice with Classic OS4.x, as maybe many people who bought OS4.0 are.
BVision / Cvision is a special case too.
CVision / Bvision in PPC cards flashed with the GREX firmware are not autodetectable so the installer will use its fall back AGA mode.
Obviously AGA installer is used if there is no graphics card.
As for removing hardware. You can keep the subway in you don't need to disable anything as only the highway is supported by sirion on classics.
You can keep your squirelscsi in that doesn't interfere with the install.
You can keep your IDEFix-Express in that doesn't interfere either.
MK3 powerflyer is supported by a new driver supplied by Elbox
That all sounds fairly straightforward, and some it defintiely applies to my hardware.
As for Z2 I have a Multiface3, DENEB, XSURF3CC, CV643D squirrel scsi and none of that needs to be removed on that for the install.
I see no Radeon in your system there, but is the Radeon GFX card memory still able to be added to the system RAM from the Mediator PCI library under Classic OS4.1?
Weve put together a large FAQ that covers all the things that came up during testing its included with CD. There is also a 28 Page Manual covering the install procedure and the FAQ is 16 Pages.
Are all my above questions included in that FAQ or in the Installation booklet, such as the Squirrel SCSI, tested software list, and any known incompatibilites, etc.?
I understood that the FAQ was going to be uploaded to the Hyperion Blog pages before Classic OS4.1 was released, to provide people interested in buying it to make an informed decision about upgrading, but I haven't seen anything of that nature uploaded there. Will it be uploaded there soon?
A lot of which is on the hyperion blog at hyperion-etertainment.biz
The ones I still use off the top of my head:-
FinalWriter 5 / 97
MakeCD 3.2
TVPaint
PPaint 8
Photogenics 4.4
IBrowse 2.4
Term 4.8
Ftpd
TurboCalc
CodeAudio
OK, I've asked about a few more, so I'll wait a few days for your report on whether they are compatible or not, hopefully they will be.
But have migrated to OS4.X equivalents for most other things like pic viewers, mp3 players
Only natural you would, so you can test them, and also if you're happy with Classic OS4.1. Would you say you were happy with it as it is?
What else would you like to see included, particularly that would benefit the Mediator for Classic OS4.1?
Dual boot is easy you just need two partitions under the first 4GB on your harddrive
For example DH0 and DH1
OS 4.1 on DH0 and OS3.X on DH1, make them both bootable one with a higher boot priority than the other. Your Amiga will boot from the partition with the highest boot priority. Just swap the priorities around in hdtoolbox or mediatoolbox and save then reboot.
Just make sure that the 68K l:fastfilesystem and l:smartfilesystem are in the RDB on your HD. The ones from l: not the ppc ones from kickstart
How do you put them in your RDB? Are you talking about during initialisation and formatting the drive with fastfilesystem or smartfilesystem, or some other method of putting the files in the RDB?
I have mounted a CDROM with the squirrel, but have not SCSI HD to test a HD.
I have also added the device to the kicklayout as a default kickstartmodule and the system booted ok.
I'd still like a small tutorial on the kickstart and kicklayout modules and other system boot files, and how they affect the system booting, either here in this thread or in the FAQ that should be available on the Hyperion Blog, or upload it here if that's OK.
