Unless you use an electronic performance based calculating tool like a BLT, OPT, or you tabular presentation is different to the standard Boeing presentation, then with Anti-Skid inoperative, you use the normal dry field limit and obstacle limit weight.
I include a link to the Boeing 737(800) Flight Planning and Performance Manual which I found off the net. The relevant text is in section 1.1 Takeoff and landing text, P20/294. This is a 2006 version and it is the same as my initial Boeing manual dated 2000 as well as my current performance manual dated 2010.
Hope this helps
