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.
