EFIKA OpenFirmware RECOGNIZES TWO ATA Devices
!!!, but MorphOS don’t.
This topic is long, if you don't want read it, questions are at the end - paragraph 5. 1. Efika and ATA
At many forums was discussed, that is impossible to have two IDE devices in Efika5200b.
CPU 5200b manual says, that ATA provides full functional compatibility with ATA-4 and here is only mentioned, that signal CSEL is not connected. I think it can works, when devices are marked with jumpers like master/slave.2. Working configuration
After reading many manuals and wikis and many tries, I have this (partially working) configuration:
i) special home-made 44-pin cable( M-F-F, pairs are crossed between M-F). The crossing is really needed!! I can explain, if there will be interest.44pincable.jpg
ii) adapter 44pin IDE -> mSATA SSD, with home-made additional power connector, to supply IDE bus, conected as master.Adapter1.jpgAdapter2.jpg
iii) Kingston mSATA - UV500 120GB SSD
- partitions: bi0
(Boot: with boot images, bootmenu, morphos.iso), DH0
(System:, bootpri 0), DH1
iv) ATA 2.5“ HDD WD, connected as slave (by jumper)
- partitions: DH0x
(SystemX: - old system partition, bootpri -5), DH1x
(WorkX: old work partition)
v) it is not needed, but it is listed on next screenshots – USB with MorphOS hdimg
- partition: SDH0
(MorphOSBoot:, bootpri 15)3. Open Firmware
IT WORKS!! Open firmware see all devices.
Here is pictures from OpenFirmware: devaliasOF-devalias.jpgshow-devsOF-show-devs.jpg
Above we see:
hd ... mSATA on IDE master
hd0 ... HDD on IDE slave
hd1 ... usb on scsi
here is listing of partitions of all devices:ls hdls hd0ls hd1OF-ls-devices.jpg
On every device we see correct numbers of partitions with theirs names and type.
here is listing of first partitions of IDE master and IDE slavels hd:0OF-ls-hd.jpgls hd0:0OF-ls-hd0.jpg
On every partition is correct files, can be listed and can be booted from(see next paragraph).Efika OpenFirmware recognizes TWO ATA devices, and can read from them.4. MorphOs don’t recognized second device
Unfortunatelly after boot (i.e. load boot.img) MorphOS recognized only ONE device.Try boot from IDE master:
boot hd:0 boot.img BD=DH0 (with USB inserted)HDD2-scrrenshot-hd.jpg
boot hd:0 boot.img BD=DH0 (without USB inserted)HDD2-scrrenshot-hd-B.jpg
Here is ramdebug (only one device seen)
Try boot from IDE slave:

boot hd0:0 boot.img BD=DH0x
it allways hangs (with/without usb inserted). Probably becouse MorphOS boot.img don't see DH0x on ide.device:1
boot hd0:0 boot.img BMBootMenu.jpg
No second drive visible.5. Result and questions
It looks like Efika firmware(with appropriate HW) recognized two devices on IDE bus.
It looks like MorpOS don't recognize second device on ide bus on Efika. Maybe driver simple don't count with possibility of second device.
I have some questions:
- Do I make some mistakes in my procedures?
- Do I make some mistakes in my conclusions?
This all not just for fun - if we can use two IDE devices, we can connect DVD on IDE bus, and not stay limited to USB 1.1(1.5MB/s).
Special question for MorphOS devs - please, can you confirm that ide.device for Efika recognize only one device? Of course, if you have time look at this.
