Can I put the TOS4DFB1 Image in a Eprom and put it onto the Falcon Mainboard ?

Yes, I think it should be safe.

Well that's nice, first time I've seen the TT-RAM test on my Falcon outside of a test version of EmuTOS.

We've broken the totaliser, mind.

...and there's the FRB. First thing in memory.

To test it, I've just loaded the README file from the HDDriver 11 floppy disc, and sure enough there's some of the data in the buffer.

So the big question -- do SCSI drives now work?

I just flashed this new tos to my dfb1. It still boots up ok with icdpro and sysinfo shows the ttram. Nice! Thanks.

Cool. Are you an ICD man usually, or do you have a copy of HDDriver you could do some tests with?

Ta,

ICDPro, I'm afraid. I do have some SCSI disks though haven't tried them since I reinstalled TOS and ICDPro on the CF.

No worries.

If you do happen to get your SCSI discs out and have the time (and don't mind erasing the SCSI disc in question so it can be set up with a tiny boot partition), then the HDDriver demo is sufficient to test with.

What we're trying to establish if doing this with TOS allows HDDriver to boot from and read and write data from TT-RAM.

Something as simple as loading FRONTBENCH with the TT-RAM flags set from SCSI ought to prove the point.

Cheers,

Incidentally, I'll publish my patches and the patching tool I used when I get around to it -- I'm afraid I didn't employ TOSPATCH.

I might have a chance to do so at the weekend. I checked plugging them in at least to see icdpro identify them though it didn't show the partitions on the desktop. Its a bit fiddly you see because they are in a rack mount case and I can't access the dfb1 or cart port when its all together. So I need to take it out to somewhere accessible.

Do all the hd drivers use the same partition format? So I can switch driver and expect to still be able to see partitions?

@markus0321, do you want to have a try with this?

This is a nasty hack, but might be a good data point.

This is a version of TOS404 that:-

1. Detects TT-RAM
2. Maddalt()s the TT-RAM
3. Reserves an FRB
4. Sets the _FRB cookie

You do not need MAPROM or FASTRAM with this version of TOS.

So the question is: does HDDriver bootstrap itself from C: now?

EDIT: see next post.

Hello. I have a son in the hospital now and I haven't had time for the last few days.
I'll try to check it tomorrow after work.
Thank you for trying to solve the SCSI problem.
