I tried to find out more about the IDE speed issues on my 486 VLB system. On second look, it is not an Award BIOS issue, nor is it Cx5x86 specific. Since I got the same low 1323 kB/s IDE speed with the original AMI WinBIOS from 1993 using an Am486DX4. That is with LBA, Block Mode and 32-bit enabled …

DOS 7.1 seems to run OK since it works with the start of the disk. But Windows 95 setup ScanDisk will try to access the last cylinder of the partition, and will show an error when unable. I always choose 98se over 95, so I hadn't ever encountered this. Thanks for the tip. It should not matter …

Also the lower IDE transfers speed of this Award BIOS troubles me. I just found out about this conversation. Very interesting. Also quite a coincidence, just as I am hitting that roadblock with the exact same Award BIOS and its DOS IDE speed. (Though I haven't yet put back the AMI WinBIOS to cross- …

I can finally post an update about this 486 VLB system. It was in limbo for a long time. But I recently decided to just finish things in a quick way. Especially the interfacing at the front of the case, so I can put the cover on the case. I cheated using quick tie-rib fixtures. What changed since …

Any updates? Not really. I concluded that the way OpenDune interfaces to the different sound and music drivers, is not suitable for slower DOS machines. The way the project is set-up now, it is not possible to ADD proper DOS drivers. It can still be implemented of course, like forked and changed …

Since the ThinkPad 380Z has no gameport, you cannot attach hardware to the MPU-401's midi-pin. So that is like a dead-end. - You can try the VDMsound trick in the link, of course. - Maybe someone could tweak the driver configuration so it reverts to the microsoft sbemul.sys. I currently have no time …

Yeah, the Windows 9x Dos Box does not have its own MPU-401 Midi interface, it is up to the sound card driver to supply such services. And even then, like 99% of these drivers do not allow you to freely route midi to a Software Synth of your liking. VDMsound can do it, but it is tricky and uncommon. …
