I have not heard what approach KAL801 was flying. Guam International has several approaches. Field elevation is 297'; runway 6L touchdown zone elevation is 256'.' The ILS (NOTAMed out?) has a decision height of 456'. The minimum descent altitude (MDA) for the localizer only approach is 560'. The VOR/DME approach has a 660' MDA with the missed approach point 2.5 miles past the UNZ vortac and .8 short of the threshold for 6L. The UNZ vortac is at 680' MSL. Since the impact site was close to the vortac, one news report speculated that the pilot was looking for a zero DME reading for the threshold which would put him at the 660' MDA over the vortac. (The vortac at Kimpo Airfield in Seoul is at midifeld.) Another report implied he was flying the VOR approach which has an 860' MDA.
