Hi.
I have HBdos and I use BEER IDE but I want to run DOS2 for MSX2 + I do not know how to install on the MSXDOS 2 partition so that BEER will run not with HBDOS only MSXDOS2. I have a diskette image and I made a DOS2 floppy. When I try to run from a DOS2 floppy, it will not be started by BASIC in capital letters only. Help me do it all in order - I am new to MSX ...

I am not sure about the BEER device. But for DOS you need a DOS2 rom as well. So only a disk with the DOS2 executables is not enough. Most IDE or SCSI hardware expansions have a DOS2 ROM inside. Not sure about your hardware.

No, this one does not have DOS2... you have to plug it to another slot.

So how do I get a BEER out of a floppy disk slot and I do not want to run like that because I miss something? I am a beginner in MSX. And please explain what I need to run DOS2. Need some cartridge or ep-rom mounted on the motherboard for my MSX2? I got lost a bit.
I can not also run Sofa (or I can not) on BEER?
Some programs need DOS2 ... oO

I don't think there are many users around, who have experience with this interface... or if they have, the experience is from 30 years ago or so... If manuals can't help you, you may need to go with trial and error method. From technical point of view this is extremely simple device, but I have no idea about the software side.

Both of these are valid options, but I would say cartridge is more easy way to go. Please note also that DOS2 needs minimum of 128KB memory mapper RAM to even start.
Example:

As I said, I'm not expert on the subject, but I don't see reasons why you would not be able to run Sofa tools. I think at least most of them work even without MSX-DOS2.

Yes... but the amount is not great. DOS2 programs are mostly different kind of tools.
I would say the reason people use DOS2 is not so much about the programs made for it, but the fact that this OS version introduced a new and very handy concept called "directories" that are sometimes today also called "folders". This feature made it possible to place programs to their own groups and place only link to this new group to the "root" of disk. As a side effect this also made it possible to store more than 112 files on a disk. With floppy disks this feature is not so special, but it becomes useful very quickly when you start using hard disks.

It might very well be that this version is not compatible. I would try a regular version of MSX-DOS1 at least first.
The general idea is that first you need to attach the hardware. Then run the BEER IDE partitioning tools to divide the disk in to partitions (Under MSX-DOS1 I see no reason to create bigger than max 5MB partitions) and then you copy the files to these partitions. In order to run MSX-DOS1 you need to copy COMMAND.COM and MSXDOS.SYS. If you get later MSX-DOS2 cartridge, you can create even 32MB partitions.

If you feel that you are beginner and you are not that much into experimenting your self, I could also try to suggest in a conservative way that you place the BEER in to your collection shelves and buy something more recent from this millennium... like Carnivore2 or MegaFlashROM SCC+SD. This way you will get much less gray hair during the process and you will find support much more easily.

THX!!! Big smile
So I need a DOS2 cartridge. I have to do it ...
And now: what are the procedures (commands) to run through the Sofa - .dsk, .rom, .cas, etc. Can you tell me?
And Romload shows me the message that I do not have sound card and also does not start - are there any startup commands? I do not have an SCC card.

If you plan to build it your self, here you can find circuit diagram:

This software set is very well documented in the readme-files. Please download the latest version and check them out. If you download the SofaRun it has a nice GUI for the SofaROM, SofaRunIt, SofaCas & other tools settings. The developer (Louthrax) is also active and usually very helpful in case there is something that you don't find from the manuals.

You can find his tools & homepage from here:

I think by default it tries to use flash cartridge... You may need to ask it to use memory mapper instead. The parameters for this should be in the already mentioned manuals. (Or in SofaRUN configuration menu)

hmmm ..... as described in the link provided, I need MSX-DOS2 to run SofaRun ... i.e. I have to make or buy MSX-DOS2. ; (

Ah, ok... I thought it only had "DOS2 support", but indeed it may be requirement... I believe the SofaROM works anyway without DOS2?

BTW If you build MSX-DOS2 by your self, I would maybe take 1Mbit ROM instead of 512Kbit... (and connect D3 & Q3 of 74LS175 in the pic) This way you might be able to put Nextor to the ROM... Nextor is kind of "MSX-DOS3"... That might enable you to use FAT16 partitions as well and get rid of the antique BEER original partitioning tools. (Not a promise, but idea worth a try if you do the cartridge anyway)

That would be a good solution, but I do not know if I can handle this task.
And does any of the type, MR or GR8NET cards have MSXDOS2 or MSXDOS3 in them?
