Unfortunately, the only cd drive I have to test is an internal LG one from 2000. Interesting though that they look the same.

Good to know! As for the cdrom port, could I just add an IDE cd-rom drive to it? Or would I have to stick it into the parallel port?

Welp, I took off the jumpers and reseated them a few times and… it works! Kicking myself though, should’ve done that first 😖 Sbdetect and hwinfo are helpful programs to have around, but they both give me A240 as the I/O port, different from what people here have been telling me. Any reason for this? …

Would HWinfo be this one? HWiNFO for DOS resurrected !

So it sorta works? Running at 22 produces very quiet, garbled sound. 44 doesn’t work at all, track position doesn’t increment. This recording was taken with the sound card volume and the speaker volume at max. The previous forum I asked this question on suggested that there was a jumper for speaker …

After posting that, I realized that my settings didn’t match the BLASTER command, so now music does work, but sound effects don’t 😒

Music Sound Card - SoundBlaster, port address 220 Sound FX Device - SoundBlaster, port address 220, IRQ 7, DMA channel 1, Sound FX 4

The machine is a Compaq Deskpro 4/66i. I do admit, I haven’t tried many games. Prince of Persia works, Paku Paku works, Doom didn’t, I assumed a problem. Any other games that could point out an issue?

Interesting, I never considered the possibility of a cd-rom drive. I also didn’t see the obvious label above the plug… I’m sure someone smarter than me can decipher the mystery plug (some sort of 25 pin cd drive?) As for the original question, is there a reason that the card isn’t working? First …

Wow! Thanks for that! Should I redo the continuity without the jumpers? Anyways, the Set Blaster is currently set to the basics (220,7,1,3). Is that an ok assumption? As for the CD-ROM port, do you mean the pins on the far left? That’s for a parallel port.

Alright! So I've tested the continuity and came back with a (probably) poor way of showing it. I don't know if I did this correctly?

Been a bit busy. Finally getting back to this. I don't know much about motherboards and traces, but I'll try my hand at multimeter continuity testing. In the meantime, I'll post some photos in case that helps anyone.

It's a SB 2.0 clone, no drivers necessary, just set the BLASTER environment variable in AUTOEXEC.BAT, eg.: set BLASTER=A220 I7 D1 T3 But! ES488 itself lacks synthesis indeed. For full SB compatibility, FM synthesis is necessary. Hopefully there is some OPL2-compatible chip on your card. If not ( …

Heyo, I have an ESS ES488 card, and while it does work, some games/programs don’t seem to work with it? For example, Protracker II doesn’t emit sound and Doom doesn’t play music. I assume this is because it doesn’t do music synthesis, but I wanted to ask just to be sure. If that’s not the case, are …
