Testing upper 256 KB video memory in ISA VGA card

I have a ISA Paradise vga with 512 kb video memory. How I can test the 256-512kb memory range? The checkit and other testing utilities test 0-256kb video memory range but not 256-512kb memory range. How I can test that range?

Get one of those Startech S370 coolers and stick a Noctua on it? That's what I've done and I can barely hear the small fan from inside the case Startech S370 with Copper Heatsink https://i.ebayimg.com/images/g/N38AAOSwL-9cki3I/s-l1600.jpg with NF-A6x25 FLX https://images-na.ssl-images-amazon.com/ …

Hi! These days I'm trying the OS/2 1.3 operating system and I found a problem. I read that operating system has support for SCSI CDROM (I have a Toshiba SD M1401) and I would like to test . For the test, I took a 486 class machine and that SCSI CDROM in a adaptec 1542 SCSI controller. I never get to …

Hi! I have a Paradise VGA card (PVGA1A) and I would like to install OS/2 1.3 with that card. I searched for drivers for that card and I only find this file: PVGA_12.zip. The file_id.diz says: "Paradise VGA For OS/2 v.1.2x." When I use that disk, I get three options: 640x480 256 colors 800x600 16 …

Another question. I've seen there is two revision of the motherboard, but I haven't seen any visual differences. How I can know what revision is my motherboard? https://stason.org/TULARC/pc/motherboards/F/FIRST-INTERNATIONAL-COMPUTER-INC-486-486-PIO-2-REV.html https://stason.org/TULARC/pc/ …

This is referring to the sticker on your motherboard's BIOS chip. At the image in the link, at the bottom right of the image (upside-down) to the right of the CMOS battery, the sticker has an 7-digit code (103C701 in the picture). http://www.amoretro.de/wp-content/uploads/fic_486-pio2_486_pci_ …
