There's a thing that i still dont understand, i compared 2 boards (asus prime z390-p and this one) and on the comparison website, there was this graph https://prnt.sc/v7bkzf, and on the board i wanted to buy it said that rom is not applicable, thats why im confused.it does but only for its BIOS it uses. all BIOS's on motherboards are on EPROM's not Plain ROM Chips. its not something that you can Use for other things as its what is used to just hold the BIOS for the board to function and is either 1x16MB EPROM or on newer boards 2x16MB EPROM's like the new AMD 500 series Motherboards as AMD's BIOS's are so Bulky.
from what i can tell it has a Winbond W25Q128JV 128M-Bit (16MB) EPROM on it its just not listed as its not something that Needs to be in the specsits just due to MSI not listing that on the site thats all as all that is doing is pulling that DATA from the Product Website. its impossible to have a BIOS without a EPROM on the board its just MSI doesn't list it as a feature as it makes absolutely no difference to a end user and is just useless data.
