Hey everyone! Just got my hands on the Orpheus II and began my journey to get it working on my pc.
The system is IBM PC 330 type 6577
it has a Pentium 200Mhz MMX CPU, 80+smth (4*16 sticks plus extra special IBM stick) RAM
Voodoo PCI GPU
details are here(haven't updated yet)
also i added the 16mb fpm memory stick to the Orpheus.
my main OS is Windows 98 SE, so i began by installing the drivers there.
Unfortunately, my first experience was the terrible screeching sound on windows startup, see for yourself: https://youtube.com/shorts/uRxD3AKY3hA?si=vhj6_v6T9nG6d2Y_
This is what device manager show me:
i checked the sound output devices, and this sound distortion is happening when the "Ultrasound CODEC Wave Driver" is selected as an output:
when i choose the Ultrasound SYNTH, the sound seems OK
but when i choose the CS4236 the sound loops (for example, when i move the windows volume slider, the sound repeats itself about 20 times)
well, as the most obvious place to start, i dived into the IRQ headache.
as it happens, the IRQ 5 is occupied by LPT1 port:
Which is very weird, because i disabled the LPT, COM and infrared in BIOS. Ok, let's go to the BIOS. Indeed, they are all disabled
but it's obvious now that they still occupy their IRQs. Only thing i can do is change the IRQ for LPT, and the only options are 5 or 7 - and both of them needed for crystal chip and GUS on the Orpheus.
when i change the LPT IRQ to 7, Crystal chip began functioning properly , but there's no more GUS in devices:
So i suppose there's no way to truly disable these ports on my machine in order to free the required for the Orpheus IRQs, which makes me very sad(
Maybe there's some workarounds you can point me to?
Or the only option is to change the PC to something more versatile?
