Using IDE image in RPCEmu

Hello

I have imaged my old RiscPC 600 HDD by plugging it in to my PC
and using ‘dd’ to dump a complete disc image.

size around 2GB
hi all

I want to simply call this image hd4.hdf to the emulator RPCEmu from it and run it as (( ADFS::4 )) but
the emulators complains that the disc is not understood ?

btw the image i can access it from my linux without any issue

mount -o loop -t adfs hd4.adf /mnt/riscos

on other post google groups talk about some solutions by disable LBA mode by clearing byte
0×00000dba with 0×01 also talk about to add 512 null bytes to the start and end of the file using dd command

I’m not sure how can be done Has anyone else done this before ?

Thanks for any help or advice you can give.

I did the same thing recently.

In my case, I only had to add the 512 null bytes to the file, and it worked. I assume the lba bug is resolved these days.

Can you just use cat or dd again to create an image offset by 512 null bytes? I was using Windows, so found a free hex editor.

I’ve had success with these methods (dd on a Linux machine & !FCFS on RISC OS) and been able to mount various disc images (IDE, SCSI, ST506) into various emulators, some require the 512 bytes to be added, others the LBA mode changing, etc.

My notes on modifying the LBA setting:
This file has been modified using ‘HexEdit Pro’, I’ve swapped bytes 0×00000dba and 0×00000db0 which were 0×01 and 0×00 respectively. Swapping them apparently preserves the checksum…
