- Autoboot
- Works with Kickstart 1.3 and up
- Supports up to 2TB drives*
- Supports ATAPI Devices (CD/DVD-ROM, Zip disk etc)
- Boot from ZIP/LS-120 etc
- Boot from CD-ROM*
- SCSI Direct, NSD, TD64 support
ROM downloads are available under releases
Currently there are three builds
- lide.rom - Used for boards designed by me that feature an IDE interface (such as CIDER)
- lide-atbus.rom - For AT-Bus style devices i.e AT-Bus 2008 + clone, Matze accelerators etc
- lide-word.rom - For devices with word width bootroms
Booting from CDROM requires Kickstart 2 or higher and one of the following:
- CDFileSystem from AmigaOS 3.2.2 loaded with LoadModule
- BootCDFileSystem from OS 4 either:
- Added to a custom Kickstart ROM OR
- Loaded by LoadModule
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
Also make sure to use the "Quick Format" option when formatting such partitions
- IDECS1 is asserted when A12 is low and the IDE device's base address is decoded
- IDECS2 is asserted as above but when A13 is low rather than A12
- IDECS2 can instead be routed to a second IDE channel as it's IDECS1 and the driver will detect this
- IDE interface is byte-swapped
- Buffered interface
- 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
A reference design for this is the CIDER project
Building this code will require the following
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} stefanreinauer/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.
