I am trying to use giggledisk to mount a newly made ext2 partitions.

I am not sure that I am doing it right. I am running OS 3.9.

I write:

giggledisk_aos68k scsi.device to ram:

It produces a lot a of small files in ram.

I then move the file with the name Linux (the same name as my linux partition) to devs/dosdrives to automount the partition.

When I reboot nothing happens.

I have the ext2 filesystem in L and the ext2partition works on the linux side.

I have a IDE HD and CD attached to my ide-channel and I am running IDE fix.

What is the correct way to mount a Linux partition in OS 3.9?'

Thank you in advance.

@JohnFante

the partition has to be below the first 4Gb of your HD !

@lionstorm

Even on os 3.9?!

@JohnFante

OS3.9 does support partitions outside of the first 4GB for everything except the boot partition, just don't ever do a full format on any of these partitions (use quick format instead) as this will trash whatever is on the first 4GB on the disk.

I have a fully partitioned 20GB harddrive on my A1200 with OS3.9 and I've never had any problems with it, either setting it up or using it. I've never used this giggledisk thing though.

Yes! Think about it: When the machine cold boots, what OS is running on it? Yep, it's running the 3.1 Kickstart, including the old 3.1 scsi.device which controls transfers to and from your hard drive. The 3.9 ROM image with updated support for large hard drives doesn't come into effect until Setpatch causes the warm reboot which occurs a couple of seconds into booting. Only after this warm reboot is the Amiga actually running OS 3.9 and able to access above 4.3GB, so therefore the 3.9 ROM updates and other system files all have to be below this limit to be able to be loaded by the 3.1 Kickstart...

All my 3.9 files are below the 4GB limit. And the same is OS4.0 and a small boot partition for linux.

The primary linux root partition is above the 4GB limit (it is 2GB in size) and so are a lot of other partitions.

Thanks for all the advice but my questions was not the 4GB limit but how I use giggledisk to automount my Linux (root) partition.

Does anybody know that?

And as you can here it is possible.

@JohnFante

EXT2FileSystem uses TD64 commands if possible.
So if you're using cybppc.device of your CSPPC, then the partition may well be above the 4 GB limit.

But I would use EXT3 instead of EXT2 - it's more robust in case of a Linux crash.
And have you set the filesystem blocksize to 512 bytes? This is important for EXT2FileSystem to determine the correct blocksize itself!

@JohnFante

Sorry, sort of misread that post... Yes, there's no reason the primary Linux partition needs to be below the 4GB barrier once that version of Linux knows how to use the drive and the filesystem using TD64, seeing as AmigaOS has already booted by that stage. However, both the filesystem and the device need to agree on the type of addressing, so if scsi.device is being used it should be TD64 compatible. I'm afraid I don't know the specifics of the Linux you're trying to run, last time I had Linux installed it was Debian and the primary partition was above the 4GB barrier.

@Daedalus

except that os3.9 (and os4.0) is using NSD (new style device) instead of TD64 (used by morphos) for large HD support, so the linux partition still has to reside below the 4Go limit to get mounted

@lionstorm

You're right: If scsi.device is being used, then the partition will have to reside within the first 4 GB, as EXT2FileSystem doesn't use NSD unfortunately...

@ville9

Aw, pants! What way did I have it working then? I wonder if I had a funny patched version of scsi.device, or maybe I was using atapi.device or something - I can't remember that far back TBH...

I am using Ext3 and the filesystem blocksize is set to 512.

I am using a IDE HD and a IDE CD attached to the internatl IDE-controller on my A4000. I use IDE-fix under OS 3.9 (software) to be able to use the CD.

Automount of the Ext3 partition is not the most important item since I only have to copy some files over to continue a install of Debian.

Anybody who know how to mount a Ext3 partition under OS3.9?

Maby I should just write.

Giggledisk_aos68k atapi.device to ram:

I am not home right now so I can't test.

@Daedalus

TD64Patch could be modified to make an OS3.x version. Sources are available in the archive. I could probably make the changes myself though if there is interest in this.

@JohnFante

I'm afraid that you can't mount it under OS 3.9 then...
There is td64patch.lha for OS4, which adds TD64 support to NSD64-capable devices, but there isn't an OS 3.9 port yet.

But you don't really have to mount the EXT3 partition under AmigaOS:
Just use an FFS partition for file exchange between AmigaOS and Linux.

EDIT: I was too late, sorry.

If TD64 commands are not found it will use old CMD_READ/CMD_WRITE commands 32bit disk addressing.

So if your 2GB partition starts at before offset 3GB and end at offset 5GB, the EX2FS will find partition will fail tiring to read or write from the partition, above 4GB offset.

Download “scout”, it can report supported commands whit in devices.

NSD64 command does same as TD64 commands but have different command numbers, unsupported command numbers will just generate a IO error.

That's not guaranteed to work. I tried for ages to get this to mount my Linux partition under OS4 using that EXT filesystem and it just wouldn't budge. I gave up.

@Hypex

I tried it with OS4 Classic on my A4000T (NSD-only cybppc.device) and mounting the EXT3 partition worked like a charm.

@Hypex

I have a GUI based tool some where that might be helpful, I might upload it OS4 depot if you’re interested.

And I know I uploaded a tool to read PC partition tables, OS4Depot is blocked at work, so I can’t check the name of file right now.

Perhaps you could give some hints on how you got it to work?
