Re: ASUS eeePC 701 / 4G FSB Adjustment Utility

Posted on 2024-04-14, 02:29

in DOS
Yes, i945 chipset and GMA950 graphics / vbios on Acer Aspire One. Perhaps GMA900 vbios can be hacked to do native 1:1 instead of stretching by default. I looked and can see that no one previously has released such a utility / hack for the EEE701.

Thanks for confirming 800x480 display! I found a way to map 1:1 native pixel mode, thereby disabline stretching on my Acer Aspire One, through a custom video BIOS driver from Intel, but of course I don't think that will work for the Eee701. And, it takes up about 64kb of low DOS memory to do so, as …

Hope it is useful, that native 640x480 LCD really does look neat playing some old titles. Everything I've read says that the screen on the eee701 is in fact 800x480, not 640x480. Is the screen 4:3 native or is it 16:9? Clarify if you can. I didn't think any netbooks had a 4:3 screen. I have an old …

I have also problem with very low output volume (maybe 10x lower than SBEMU or MPXplay) on my SB Audigy. I though it was just a specific issue of mixer setting of my soundcard type... Did you see this posted on Dos Ain't Dead, posted by Japheth? It's not "halved", it's using kind of a "geometric …

Jazz Jackrabbit definitely has MOD tracker music, not FM synth. I believe you could set the mixing/sampling rate in the settings in the menu, to match with the performance of the system. Maybe you can play with that, to see if you can get the music to work that way? I got Jazz Jackrabbit working …

- Jazz Jackrabbit - I get only some of the FX sounds, like shooting(not all weapons), jumping, bubping(sometimes). No music at all(it's not FM , but PCM, right?) - Tyrian 2 - sounds in menus work, but when the level starts - the game freezes. Did you download the latest pre-release? There was a …

There is a new version of VSBHDA out which now supports 16-bit protected mode games. I successfully tested it on Jazz Jackrabbit and Tyrian 2k on an i5 8th gen Dell laptop with Intel HDA . Thanks to Baron von Riedesel's spectacular efforts, the sound is working and we have another hurdle overcome on …

Re: FastDoom. A new Doom port for DOS, optimized to be as fast as possible for 386/486 personal computers!

Both cases are optimizations. Removing the turbo command allowed us to have a fixed value for movement, which enabled further optimizations in P_MovePlayer and G_BuildTiccmd. Removing the nomonsters command lets the maps load a bit faster, something a bit frustrating on slow 386 cpus. I see. Well …

Please try to get it working in DOS. It's the perfect DOS game. I appreciate your efforts and always like to see new 'retro' homebrew stuff. This is great, frenetic action. As has been stated above, you can easily convert the colors to 8-bit and this wouldn't even degrade the quality of the game. …

Whatever you do, don't buy curved. Intentionally introducing gross physical distortion to the image? Why bother actually *paying* good money for that abomination? Stick with an OLED non-curved 16:9 monitor, and you'll get fine outstanding image quality with a lot of nits. Yes, go for at least 1000 …

Re: SBEMU: Sound Blaster emulation on AC97

The only issue I can see in your report is that the LAPIC timer is demasked. It's routed to INT 5, which is odd, because it "should" be >= 0x10 to work. So it's "activated", but almost certainly dysfunctional with those settings. However, that's surely not related to the "invalid" sound IRQ. That …

There was a version of SBEMU which did enable IRQ > 15. I believe it was the 5 Feb. 2024 version. I have the same chipset and CPU as vanfanel (Apollolake with Celeron N3350 and Broxton Intel HDA). However, on the 5th Feb SBEMU, it appeared to work (ie, did detect IRQ 25 as being valid), yet still …

EDIT: this zip will use real mode PCI bios to assign IRQ, you can test if it works: Just tried the test version you posted on my E100. It fails with same message as other versions of SBEMU before 4th-Feb: "Detected Intel HDA at IRQ 25, Invalid IRQ, trying to assign valid IRQ" and then aborts. It …

How mpxplay do sound playback without IRQ? Does it poll for playback current buffer position? As it can do decoding in small chunks and nothing else to do it's probably no problem. Legacy BIOS should probably map all IRQs into range 0-15 using IRQ sharing when there are more IRQ sources. On modern …

Re: SBEMU: Sound Blaster emulation on AC97

That's really interesting... Usually there's APIC on non ISA machine, but not enabled by BIOS by default. Currently IRQ above 15 is treated as invalid, I'll change to 0xFF instead, on next release. :) OK, crazii, thanks for enabling IRQs above 15. I tested the latest 05-Feb userbuild of SBEMU on …
