Hello VCF, I need some help with an Intel 80186 Computer project I am designing. A while ago, before my reddit account got suspended, I made This Post on the r/beneater subreddit. A user replied to my post saying "To add 1MB of Memory you need two 8bit 512K chips (lower, upper) and connect them by A0/BHE and the other pins."
Since I do want 1MB of RAM for this project, how do I include a ROM?
If I have 2 512k SRAM ICs for the 1MB of ram, how would the 80186 find code to execute? or was that reply talking about 1 512k SRAM and 1 512k ROM chip to create 1MB total memory?
However, if I do use 2 512k SRAM chips, is there a way to add an ROM chip with the x86 code, or is the Memory Map just full of RAM now?
Unlike what that Reddit Post says, I no longer want to create an PC-Compatible Computer with the 186, I'll code my own OS for this Computer. I'll create another post about this project when I have an idea on what to do with the Memory Chips.
Any help, information and advice will be thanked in advance! Thank you for Reading!
