u 1: Boot Scan delay....manual shows no 
     jumpers here in default configuration 

u 2: #1 (left) jumper is 'Enable I.C.P. 
     (Yes/No)', middle 6 not used, 
     #2 (right) is 'multiple initiators (Yes/No)' 
     manual shows no jumpers in default configuration 

u 3: Selection phase time out delay..I believe this 
     sets how long the card waits for the drive to 
     come up to speed(?)...manual shows the default 
     as having 4, 5, and 7 with jumpers installed 

u 4: Arbitration phase time out delay..
     manual - default no jumpers installed 

u 5: Bus Free phase time out delay..
     manual - default has jumper on number 1 

u 6: Interrupt recovery delay....
     manual shows jumpers on 3, 4, and 5 

JP1 and JP2 are single sets of pins. 
Manual - J2 is not used, J1 is jumpered. 

    My card has the following jumpers set 
    (for use with 1990 ROM only): 

 u1:  jumper on 7 
 u2:  no jumpers 
 u3:  jumpers on 4, 5, and 7 
 u4:  no jumpers 
 u5:  jumper on 1 
 u6:  jumpers on 3, 4, and 5 
 jP2:  no jumper 
 jP1:  jumper 

    This setup yields a rather long pause for the 
    hard disk to come up to speed (about 40 to 45 
    seconds) that they found necessary at the time 
    to avoid boot problems. However, being my hard 
    drive can be started prior to starting the IIgs, 
    this could be shortened provided you can figure 
    out the settings. Good Luck.
