Or bad .. SymbOS is complex enough to understand itself and its own existence and will start a war against the human race. Oh wait, that was Sky(-pe dot-)Net.

LGB, please note that SymbOS is designed to follow Isaacs three laws of robotics, so you don't need to be afraid, that your Enterprise computer will misuse the technological singularity which it will reach very soon :ds_icon_cheesygrin: :ds_icon_cheesygrin:

But Edoz is right :P Have a look here: SymbOS playing videos from Sd card on the Enterprise!
https://www.youtube.com/watch?v=oW4LTVcP9x8

Today I got the SD card interface working in SymbOS: Gergely and Zozosoft, you made this possible!
So of course the first thing what I tried was to play videos, and that was working quite nice.
The picture on my monitor is still crap, as I didn't receive a SCART cable since one month, but maybe there was something wrong with the shipping address.
And sorry, the Control Panel still shows "IDE" and "Master/Slave" instead of "SD card" and "Slot 0/1". I will fix this + some additional things for making it possible to boot from SD card without the need to have a disc drive anymore.
SymbOS supports EXDOS floppy disc drive access and SD card access at the same time. What doesn't work right now is SD card swapping. Please let me fix these few issues before uploading the next version.

CU,
Prodatron

PS: The picture of my Enterprise is getting worse and worse depending on the runtime of the computer. After 30-45mins it's completely crashing. It's getting quite hot on the upper left side. Hope this isn't a seriouse problem?

I assumed, however especially "I, robot" and similar Asimov writings is about the chance that there are no perfect laws, and sometimes machines should kill humans to help the greater goal, creation of the law #0 which is about the human race in once and not the rights/freedom of human individuals one-by-one. Thus I'm still worrying :)

But seriously, really nice news about the progress of the EP port! :) However I still miss the events in the "History" part of web site symbos.de :)

About 25 years ago when I'm used the Enterprise with RF cable :-)
Generally the RF tuners of modern digital TVs are terrible when comparing with old good full analogue CRT TVs.
I think very possible little change in the analogue signal make big change in the poor quality digitized signal.

Need to see it with RGB-SCART. I hope you will receive shortly.

Anyway: it is a variable resistor on the motherboard near to the left side of the RF modulator. Try to adjust it.

It is a normal. Two 7805 voltage regulators make the heat.

At least two German EP128 users ordered their RGB-SCART cables from Spain and still wait and wait and wait... :-(

Very Nice to see it working with the SD controller!!!

You need to ask Edoz how to make video's. The guy that wrote the video studio creation tool doesn't remember how to use it :P

I still have some video project for the MSX but I think I have to reconvert it to 4 colors (CPC) mode

I have a short question about drive letters:
- is it usual on 99% of the systems, that drive A-D are always disc drives?
- is it usual, that SDEXT drives are always starting with F? (as E would be always the ram disc?)
- is it possible to detect, which drive letters are existing? (maybe this has already been described somewhere before?)

The reason why I am asking:
- the boot loader should detect the existing drives and preconfigure them in SymbOS, if there is no INI file on the boot drive.
I know that I could also try to detect everything by using the hardware directly, but this would make it much easier during the boot process.

I need to have a nice beta version finished tomorrow for the 30.birthday of the EP :P

A-D are the floppy drive, E the RAMDISK, these are fixed in the EXDOS.
Expansions started at F:
The SDEXT detect all partitions, but only FAT12 types reported to the EXDOS (if the EXDOS version lower than 1.6, version 1.6 will be the FAT16 compatible version). These will be the F,G,H,etc

It is can be asked by FISH call:

Code: ZiLOG Z80 Assembler
  1.                 LD DE,EXDOSFD
  2.                 EXOS 26
  3.  
  4. EXDOSFD         DB 6,"EXDOS",0FDH

You got the FISH RAM address in DE, and EXDOS version in B, as BCD number for example 14h=version 1.4

Code: ZiLOG Z80 Assembler
  1. LD IY,(FISHRAM)
  2. LD A,(IY-5Eh) ;EXDOS ROM segment
  3. OUT (0B3H),A
  4. LD A,0FFh ;system segment
  5. OUT (0B2h),A
  6. LD A,20 ;FISH 20
  7. CALL 0C010H ;FISH entry point

Then you got a 26 bit number in DEHL, if the bit=1 the the drive exist. L bit 0=A, L bit 1=B, etc

It is will be some problem, if both SD and IDE interface used :oops:
Then first coming the IDE partitions from F to ... and then the SD partitions.
