@The Solutor. This is very strange you don't see DN, the log shows DN started and output the lines. I bet something is wrong with the timer interrupts/wake up or so. Does F12 work and bring up OSD?
I added new diagnostic logs in the new release bundle.

And not just DN, MC/NC/VC all the same they look started but they aren't visible

Yeah I thought that could be the secondary monitor (say output redirected there with an unsupported resolution) so I tried with a single monitor connected, and even swapped them.
No change.
About f12 I think no/not visible, but I'm not sure, I'll recheck and update this message, ASAP
EDIT
I confirm no F12 popoup

Okay yes, something on these systems is different. PIC has a pending irq0 (IRR=1) and IF=1 and irq0 is unmasked (IMR=F8 irqs 0,1,2 are open) yet it's not delivered count=0. So apparently PIC is not hooked up to the CPU in the default config. I'll investigate tonight.

In the meantime i noticed that you implemented my suggestion of hybrid UEFI/BIOS boot, so I tried to boot via CSMWrap.
Using the native bios option I reach the filemanager screen !! (Norton Commander is configured ATM),
Using the VBE option, it's the same as UEFI.
I can't say a lot more because, in CSMwrap case I have no working keyboard , just like on the N100 machine.
Whatever I wasn't able to boot the system a single time via CSMWrap with older releases, the ones that worked in UEFI mode.
Okay I released a new version that might fix the issue (tentatively). Likely APIC didn't route the PIC irqs. There will be new log lines if it still doesn't work

The new release booted on my B75 machine but still fails at the same place on my H97 and X99.
On my B75 machine it did manage to configure my dISAppointment to the point it picked up my SB16 DSP (CT2290) but I'm not getting any sound output.
- There's no volume (mixer) control for SB16 audio. There's an option to switch to kernel mixing but it doesn't do anything at the moment.
- CT2290 doesn't have IRQ/DMA jumpers and defaults to some arbitrary IRQ and DMA numbers like IRQ10 and DMA3.
- Normally DIAGNOSE can be used to change its IRQ and DMA assignments for such "auto-init" cards to those specified by BLASTER environment variable, and this is also supported by UNISOUND.
- This is an ASUS board. The LDRQ1# is set to GPIO23 by default on this board so it needs to be toggled for DMA to work.
- Not sure if there's any option to switch between HDA and SB16, as on this particular system I've kept HDA enabled for use with a few OSes that don't have working drivers for other sound cards there.
To restore LDRQ1# from GPIO23 (you may refer to my lpcexp project):
1. Read register 48h from the LPC controller (00:1f.0). Strip the last bit. On most boards this reads 0x501 which means GPIO base address is 500h.
2. The GPIO_USE_SEL register resides exactly at the base address retrieved from previous step. Perform a 32-bit I/O read there.
3. Check the value read from previous step. If bit 23 is set, unset only that bit (keep other bits unchanged), and write the modified values back via 32-bit I/O write.
Once done, LDRQ1# will regain its native functionality and DMA will work.
NOTE: It's advised to first read the register 4Ch and check its bit 0 status. If this bit is set it means GPIO control is locked and you cannot make any changes.
However, I'm yet to see a board whose BIOS actually locked the GPIO registers so in most cases this is optional.
FYI: You may consider widening the supported chipsets down to ICH6. This will allow the initialization to work on the original board that featured this LPC-ISA design, RUBY-9719VG2AR, which used ICH7.
Additionally, so far I only had success with ISA PnP with ASRock boards as well as RUBY-9719VG2AR. On some other boards (e.g. ASUS ones), it seems only ports below 3FFh can be routed to LPC-ISA bridge, so no ISA PnP or other functions that require higher I/O ports.

Ok, it finally works, tanks. 😁
But this time a lot of additional consideration needs to be added:
-------------------------------------------------------------------------------------
Modes:
It boots both in UEFI, native CSM and CSMWrap
In UEFI I got the 4/3 aspect ratio, with fonts scaled according the 1440x900 native resolution ( practically 1200x900) in not that pleasant way
In CSM --> native video bios mode, the screen is scaled to 1440x900 (so stretched to 16/10) but with very nice looking smoothed fonts
In CSM --> VBE mode , same as above, with smoothed fonts, but not nice looking as above
The strangest part is that if I use the VBE mode AND persistent disk, I have no keyboard (I can't see the relationship, but that's what happens)
-------------------------------------------------------------------------------------
Programs:
VC 4.05 works
VC 4.99 --> too big to fit in memory (not yet tried to set it as default boot program)
MC --> bad filename or executable something like that, (from the log, setting it on boot: "Windows PE exec failed (home/retroos/CONFIG/MC/MC.EXE): errno 2")
Everything else I tried seem working OK
-------------------------------------------------------------------------------------
Other issues:
My second USB keyboard (which is what I'd like to use normally) is still non functional (albeit it's illuminated, so somewhat detected and enabled but not initialized correctly)
I see correctly my partitions, but as I wrote before I cant see the games bundled in the downloaded images.
-------------------------------------------------------------------------------------
Intel N100:
not yet tested.
@LSS: At least some progress. I tried to address your gpio/ldrq issue and widened to ich6. I kept HDA as a kernel mixing backend to choose even when SB is available. For the other platforms if there is a way to give me a log that might be valuable.
@Solutor: Can you give me the boot log of the VBE-mode + persistent disk? It makes no sense. The second keyboard might work now and the games should be visible.
Release is updated.
Overall many thanks for testing this on your hardware! I know RetroOS is still rough around the edges, but at the moment I'm focused on getting the core robust. Supporting different hardware, making sure programs work, etc..
Nice scaling, perfecting sound mixing etc. hopefully come soon when the system runs well. Btw. , the source is deliberately distributed "do what ever you want to do". Feel absolutely free to play with it, add support for some cool retro hardware like dISAppointment, workarounds like EGAFIX for your system. And if you like to merge it in, make a PR on my repo.
Ok going to downloading the new image, please wait.... 😉
In the meantime this is the log *still from the old image*, with not working keyboard (CSM/VBE persistent disk)
(BTW it worked once, when I rebooted, second boot no keyboard, it may be a timing problem, IDK)

P.S. unrelated to RetroOS itself, I think, but when i download the img file, it's always downloaded twice, the first time the download reaches 100%, then it restart from 0%, then the download is finally saved (no manual intervention needed, but still a bit strange)
Ok, few quick runs with the new image
Games folder are now visible, good 😉
In UEFI mode, finally, seems that the "problematic" keyboard works, at least if connected alone, still not working if connected together with the other one.
In CSM mode i didn't test thoroughly the problematic keyboard behavior, but I tried to understand what happens to keyboards in general.
It seem that the first time I reboot from windows the keyboard works, but if I turn off and reboot in CSM/VBE/Persistent disk the keyboard doesn't work anymore, that behavior seems, more or less, consistent and repeatable.
This is a log taken with keyboard KO and the new image .

Speaking of which, you understand that this way (no timestamp, no keyboard, klog overwritten on each run) all the matter becomes really time consuming, given on each test I have to reboot in Windows or Linux just to grab the klog before it gets overwritten in the new test.
So, at least temporarily, would be nice if to have klog-hh-mm-ss.txt format, or at least a progressive numbering, then when the matter will be stabilized you could go back to the actual behavior.
