Seems reasonable as both are controlled by WAX. So if > you have a GSC card in the slot you presumably don't have the adapter. Not entirely ... There are two families of 715; 715/33, /50 and /75 (Scorpio) and 715/64, /80, /100 and /100XC (Mirage or Turnip). Scorpio is based on the PCX/T chip and Mirage on the PCX/L chip. These are quite different architectures. For example, Mirage has Lasi and Wax while Scorpio has discrete logic. If you ever get the chance to compare the two motherboards, you'll notice how many more components a Scorpio has than a Mirage. The EISA adapter (Mongoose) was originally designed for the Scorpio family which predates GSC. It has an SGC interface instead, and plugs into the same slot as the graphics card. Mirage boxes have both GSC and SGC connectors, side-by-side on the motherboard. There is an EISA adapter as a component of Wax, but I believe it's disabled in Mirage boxes. It's used in GSC-based C and J class boxes though. -- "Next the statesmen will invent cheap lies, putting the blame upon the nation that is attacked, and every man will be glad of those conscience-soothing falsities, and will diligently study them, and refuse to examine any refutations of them; and thus he will by and by convince himself that the war is just, and will thank God for the better sleep he enjoys after this process of grotesque self-deception." -- Mark Twain
