Book8088 boots off a CompactFlash slot with XT-IDE BIOS add-on. You can see comparisons between my Dell 316SX (i386) and the Book8088 here - https://www.bttr-software.de/forum/forum_entry.php...p;page=0&category=all&order=last_answer

I included output from BIOSDRVS.COM that comes with XT-IDE. https://www.xtideuniversalbios.org/binaries/r625/biosdrvs.com
