@DJBase : you can also see that on the label : "neue edition", for the cards it may have it from a PC before ... and DCE had updated some "1 DMA" to "2 DMA" when the client asked for and returned it, like my 2nd Grex1200.
@Henes : Worst, with GREX1200 some RTL8139 cards doesn't allow you to go more than the BPPC menu (it's mainly rely on RTL chip revision) ! For the ones that passed this point, I should try again with new MOS Pup edition. The 68k ESS Driver make freeze MOS when it's selected in the AHI pref.
