Win98 used to do that to me back in the day. Enabling DMA on the hard drive cured it.

I second that. Experienced similar behaviour with Windows 98 Second-Hand Edition.

What sound card? Did you try another one? Neither Win95 nor 98 ever did that on any of my systems.

My Win98/440BX/P3-550/Aztech 2316 machine does this as well.

The couple computers I'm working on now do this as well - with ISA sound card and PCI sound card. I made a post about it recently and uploaded a video even - seems to be pretty normal.

HDD DMA has fixed such a problem in all cases I have experienced this.

I'll try messing with DMA. I've got a Soundblaster 16 Value 2770 and Awe32 EMU8000 board in there.

I've got Win95 C. The option doesn't seem to be there under system / hard drive. Does that mean my Quantum drive doesn't support it, or that the OS doesn't have the option? I thought B had the option default off, but could be turned on, but can't seem to find anything on C.

Thanks for any info!

Disable welcome sound 😉 I used to do this back then. Now I don't have any stuttering in Win95B and 5x86-133, 8MB, CT1740, CF card for HDD.

I'm sorry, I simply don't know. 🙁 By the end of the 90s, I started using Win98SE and never looked back to Win95.
Remember, there was in general no retro feeling for Win95 yet and 98 was a big bugfix pack.
So 95 was considered simply was it was. An unstable, outdated wannabe OS.

Edit: Good news! 😀 It seems the Quantum Big Foot series does support DMA (Multi-Word DMA, Mode 2)..

Edit: I've searched for answers and found some other Vogons thread that may help.
ATA DMA modes

Edit: I hope I wasn't too offensive. But from my experience, both Win95 and Linux used to be the #1 90s OSes for scrap yard/roadside find PCs. 😁

Increasing the MCI wave playback buffer will also resolve this issue.

No, not at all. I have other computers with 98, 98SE, 98SE Plus, etc... I had 95 on my 486, and this one is just the most tricked out machine I could dream of in the 90s, before I got a Pentium so here it is.

Thanks for the suggestions, I'm trying a few now. 😀

if I've got Daemon tools mounting a large ISO from the USB hdd I use (via a usb 2.0 NEC pci card) then it will play the noise in W98se in a choppy manner. If i dont have the hdd plugged in and daemon tools not mounted then it will play smoothly.

The system is an MVP3+ chipset, k6-2+ 550, 128mb PC133, Riva 128. nusb3.3 (or 3.6 i cant recall)

The DMA option appeared in 95B, IIRC. At any rate, it does not exist in 95 retail, and does exist in 95C. I suspect this will help if not solve the problem. Disk access on my 95A box cripples the box. E.g., during heavy I/O like boot-up, or software installation, or copying large files, pretty much nothing responds to clicks for a few seconds.

If you go to DM, get properties on your hard drive, do you not have the DMA option at all, or is it grayed out? It will be unavailable (grayed out) if the IDE driver doesn't support DMA. Might just be that you need to install your chipset (or I/O card, if applicable) drivers if that's the case.

Not there at all under my 95C. I need to try mode 2 and see what happens. Wasn't able to find the MCI suggestion either.

Thanks all.

The default setting is 4 seconds. Something between that, and the maximum of 9 seconds, ought to solve the problem.

Found and set to 9. Also running in mode 2 on the HDD, no change.

What is playing as the startup sound? I'd assumed it was the default, but perhaps it's not, and is something of a longer duration?

I've got no real Win95 hardware for testing at hand, but could it be that something is interrupting during start-up also ? 😐
When I boot my somewhat buggy, Win Me laptop, it does wildy play with serial and parallel ports for example (related to Plug&Play?).
Anyway, I just wonder what other reasons could possibly cause TimWolf's PC to stutter/jitter during startup.
