• Supports up to 2TB drives*
• Supports ATAPI Devices (CD/DVD-ROM, Zip disk etc)
• Boot from ZIP/LS-120 etc

lide.device supports the following devices:

• CIDER
• RIPPLE
• N2630
• SF2000
• SF500
• Dicke Olga
• 68030-TK2
• 68EC020-TK

• CDTV-RAM-IDE
• AIDE
• AT-Bus 2008 and clones

This list is not exhaustive, lide may also support other devices that implement the same IDE interface as Matzes TKs
Let me know if there's something that should be added to this list!

ROM downloads are available under releases

lide-update-<version>.adf is a boot disk that can update the IDE rom on the following boards:

• CIDER
• RIPPLE
• RIDE
• Dicke Olga
• 68EC020-TK
• Zorro-LAN-IDE-SATA

aide-boot-<version>.adf is a boot disk for the AIDE interface by Matze.
This interface has no boot rom so the driver must first be loaded from disk or added to a custom kickstart.
lide-update.lha contains the AIDE-lide.device file which can be used with LoadModule or added to a custom ROM.

Releases contain the following builds

lide.device supports booting from CD-ROM but requires a CD Filesystem to be loaded for this to work.

There are a few options:

1. CDFileSystem from AmigaOS 3.2.2 loaded with LoadModule
2. BootCDFileSystem from OS 4 either:
   • Added to a custom Kickstart ROM OR
   • Added to the IDE/Accelerator ROM (subject to board support)

The following boards support loading BootCDFileSystem from ROM:

• RIPPLE
• RIDE
• 68EC020-TK
• 68030-TK2

BootCDFileSystem must be flashed to the second bank of the ROM.
This can be achieved on RIPPLE and 68EC020-TK boards using lideflash i.e
lideflash -C BootCDFileSystem

For drives larger than 4GB it is required to use a Filesystem that supports TD64, NSD or SCSI-Direct
The default FFS in OS 3.1 does not support these, and use of this above the 4GB boundary will result in data corruption!

There are several options for larger drive support

• PFS3
• SFS
• FFS from AmigaOS 3.2, 3.9 etc
• FFSTD64

Also make sure to use the "Quick Format" option when formatting such partitions

• IDECS1 asserted at offset 0x1000
• IDECS2 asserted at offset 0x2000
• A secondary channel is supported when the second channel's IDECS1 is decoded at offset 0x2000 and IDECS2 of both primary and secondary channels is pulled high
• D15/14 pulled up with a 10K resistor to allow detection of floating bus when no drive present.
• IDE A0/1/2 connected to CPU A9/10/11 providing 512 Byte separation of registers to allow for MOVEM trick
• No interrupts
• IDE interface is byte-swapped
• Buffered interface
• Configure as a 128K board to permit loading CDFS from ROM (Optional)
• Hardware support of programming the flash (Optional)

A reference design for this is the RIPPLE project

Building this code will require the following

• Bebbo GCC
• Amitools
• VBCC m68k-amigaos target

The easiest way to get a working build environment is to use Docker You can build inside docker as follows:

docker run --rm -it -v ${PWD}:${PWD} -w ${PWD} liv2/amiga-gcc:latest make clean all

If you are using VS Code you can install the "Dev containers" extension which will allow you to develop with the environment ready to go.

This driver uses the movem based fast read / write routines from Frédéric REQUIN's at_apollo_device
The release of the open source at_apollo_device inspired me to work on this.

It is based on jbilander's SimpleDevice skeleton.

Thanks to Stefan Reinauer and Chris Hooper for the Open Source A4091 Driver which has also been a good source of inspiration for this project.
Chris' devtest has also been very helpful for testing the driver.
Thanks to Olaf Barthel for providing code and valuable advice to improve the driver.
Thanks to MHeinrichs for contributing improvements to the driver.
