Re: [Patch] Aztech Sound Cards

No filtering is doable. Unfortunately I'm not well educated in sound, so for me every difference is due to differences in speakers! :lol:
AD1848 would behave the same as the CS4248, unless the driver tries to identify it. AD1845 I've never seen, so I don't know if it would be easily implementable.

Re: Help Configuring xi8088 - Upper Memory and CGA Composite

I never sent a patch for implementing the UMB dip switches, thanks for remembering me. The only UMB that TEST!UMBs would see would be the VGA RAM. Not sure if PCem would default the UMB region to RAM, Sarah would know this but I guess not. For CGA composite, you should get the relevant settings by c...

Re: v17 compatibility & bug list

VGABios is not supposed to be used with "real" hardware, which is what PCem emulates (this is stated in its manual). Using it would require changes to PCem.

[Patch] Epson LX-810 Dot-matrix printer WIP code

So, COVID has taken away some of the joy of working on hobby projects at home. Until (hopefully) some of that comes back, I decided to rebase the code I already had to v17 and dump it here if someone wants to have fun. :-) See here for more information: https://pcem-emulator.co.uk/phpBB3/viewtopic.p...

Re: AMD Ryzen 5000 series.

On a Ryzen 5900x, I can get 100% with a K6-2 350Mhz + Voodoo 3 3000 at the Desktop and in some random 3D games. 85% with a K6-2 550MHz. (Of course, hard disk access causes stuttering because they are single-threaded AFAIK.)
Didn't test much else, I was just seeing what my new dev machine could do.

Re: No CD audio For Aztech Sound Galaxy

These cards came with both codecs and the drivers are tailored for either of them, without any sort of detection that I could see when implementing. So anyone using these cards should check the physical card to see which codec the driver expects.

Re: Video BIOS messages not showing up on startup before BIOS POST screen

On my real Zappa with a Pentium 75 and a Cirrus Logic GD5434 card, I can't see the video BIOS message. On PCem it blinks, but on the real hardware it disappears (because the system bios clears the output) while the monitor is syncing.

Re: [Patch] Two new models (Hyundai Super-286TR and Itautec Infoway Multimídia)

I've used the CPU speeds that the machine was sold with, but this may be related to the difference in supported CPUs in the various Zappa revisions (as stated in the motherboard's manual.) Later models were available with support for more CPUs. For example, next year's Infoway A96 used 133Mhz CPUS, ...

Re: [Patch] Show correct CPU speeds in Advanced/ZP's CMOS Setup

I initially ran away from that because of the integer speed multiplier (so I couldn't disambiguate from 100/50 and 100/66), but I just used the PCI speed for that.

It's also curious that the keyboard detection fails at 120 and 133 MHz. I didn't look into that.

This is a small incomplete patch that enables the CMOS Setup of the Intel Zappa to show the correct CPU speed. I'd like some input in the incomplete parts.
