Hi everyone,

I have posted a similar request on the Orpheus II thread, but as I know many people don't visit that thread I am reposting my request here again hoping to reach a wider group.

I have a Compaq Deskpro 486/66M (EISA architecture) and I'm trying to fit into the system a new sound card (Orpheus II) that supports many standards in a single card.

When I go into my BIOS, the computer detects 2 different sound cards, a Gravis Ultrasound and a Sound Blaster, but forces me to configure them in different slots (as at the time, no card existed that supported all of these in a single card).

I have the EISA CFG files for both the Gravis Ultrasound (!ICU01B0.CFG) and the Sound Blaster 16 (!ICU01A1.CFG), but I am not entirely sure how to club them together to create an EISA CFG file that would cater for the Orpheus II configuration.

For reference, my Orpheus II is currently using the follow HW Ports/IRQs/DMAs :
------------------------------------
Sound Blaster:

• Port:220
  IRQ: 5
  DMA:1

Gravis Ultrasound:

• Port: 240
  IRQ: 7
  DMA: 7

MIDI (GUS):

• Port: 300

MIDI (External - for MT-32 and SC55)

• Port: 330

------------------------------------

Also for reference, this is the content of the EISA CFG files (attached to the post as well):

Does anyone has experience with creating these files to help me build one that would work with the Orpheus II?

Thanks in advance.

You could maybe peruse these for some basic pointers...

EISA System Configuration - http://www.bitsavers.org/pdf/bcprServices/EISA_Chapter_4.pdf

The EISA Bus - https://ia800508.us.archive.org/10/items/eisa … /EISA%20Bus.pdf

I am trying to create a CFG file through my BIOS interface, but I have a question:

When I try to add a new Port, I am asked two values:

Starting Address (HEX):
Ending Address (HEX):

I can add more than 1 port in the configuration.

I know I need to use both ports 300 and 330... what exactly should I add on those two parameters?

Create one Port with Starting and ending Address of 300? And another one of 330? Or is there a conversion table with the starting and ending HEX addresses of these ports?

Thanks in advance for your help.

Usually ports like that are from 300h to 30Fh, and 330h to 33Fh but they may span more of that.
See this: https://www.cpcwiki.eu/index.php/I/O_Port_Sum … her_I.2FO_Ports
That is just an example and from what little I know, some those in that wiki might include the start address of the next port area.
I would try the two midi port addresses listed and see what happens....
From another source: MIDI Port 330h-331h, FM Synthesizer 388h-38Bh

Does the Compaq System Configuration Utility (I assume you have a copy given that its an EISA-based machine) not have a menu option to create new .cfg files using user inputted settings (similar to what IBMs equivalent utility used to allow).

If you don't have a copy I've attached a version probaby in keeping with the vintage of your machine (when run it'll create a floppy disk set with the utility and a range of pre-made .cfg files)...try it and see if there is a 'Create .cfg' option.

Remember that ISA .cfg files are generally less detailed than their EISA equivalents and are primarily used to restrict the EISA resource pool.

This range can depend on how the address decoder is implemented; often the decoder has a larger range that is limited by the number of address pins used on the decoder chip, in this case it could be implemented in the FPGA which allows for more granular resolution. Since it emulates other older boards, I guess it is the same ranges used with the original boards.

You could ask the developers, as they have a contact link at the bottom on their homepage: http://pcmidi.eu/orpheus2.html.

It does, and it solved the issue.

I just had to create a new CFG file with the right parameters and everything fell into place.

Thanks a lot for the help!
