Re: 386 DX40

1st I am fighting with what CoffeeOne said, later I will try what Intel486dx33 suggested. But so far, no success. With IDE100 and 101 I did what you said. I closed IRQ 15. CD-ROM is connected to the sound card IDE on a separate cable. I am pasting my config.sys and autoexec.bat What is happening, …

Re: My Big Red Switch 486

Promise EIDE2300Plus: I had high hopes for the EIDE4030Plus caching controller instead, but just couldn't get the performance out of it. The EIDE2300Plus supports transfer modes up to PIO Mode 3 or MWDMA 2. No bus master DMA. Bases cycle times on system bus clock, i.e. PIO 3 should run at PIO 4 on …

Re: DS1287A

Re: Compaq Prosignia 3080 / 486DX33

OS = Dos 6.22 and WFW 3.11 The installation program I'm reffering to is the setup for the soundcard on the CD I got with it so it should be the original drivers from 1995. Disabling the IDE-port on the card is on the list of things that I should do but I have to figure out how to do it first. As …
