I have read specs for this motherboard. The ISA support is through 3rd party controller (Winbond W83628F), not through 875P itself. IIRC - 865PE/875P have built-in ISA support, but - no DMA and no NMI.
P.S. Motherboard have "Disable L1 and L2 cache" option. It can do this for Pentium 4?
I started taking retro (dos gaming) computing up again, using a motherboard like the one described here.
It was a motherboard, taken from an old HP D530-SFF computer. It had 8X5/ICH5 chipset combination.
The problem was, that even if I set the "non masked interrupt" in the bios correctly. (think it was that)
The machine would drop all SB16 emulation using the SB-LIVE card and all other PCI based soundcards.
The machine did not have physical ISA slot. Never the less, it had some sort of ISA support (for max 20 min.)
Then I had to do a cold start, having turned all power off. It was defect or just prtial ISA supported.
Now I do PCI soundcards only if the board have physical ISA slots if I need to do DOS computing.
If someone could find the complete specs for the D530-SFF board, and look into the Chipset/Southbridge
combination of this machine, then we might have some of the absolutely last ISA supported technology.
Well... Partially ISA supported, that is.... 🤣 (I have not found any tech-spec doc's online)
As for the mobo, well....
It went to the trashbin, after I started recieving boards with physical ISA slots. Well...
Not until I desoldered all the capasitors from that board, and then it went "out the window".
Don't eat stuff off a 15 year old never cleaned cpu cooler.
Those cakes make you sick....
