T he C rom em eo ST X board is an intellig ent hard-disk eontroller, u sing the

ST-506 standard interface to support a w ide variety of 5-1/411 W inehester drives.

A n S'rm -eontrolled drive can have u p to 16 head s and 1024 ey linders.

A s an intelligent disk controller, the ST IX needs little attention from the host#

ting sb' stem . W ith its ow n Z 8OA m icroproeessor, 641( by tes of R A LI, andopera

direct aeeess to m ain m em oc (D M A ), the ST X allow s the host C PU to eontinue

exeeuting instruetions during disk read/F rite operations, relieving the disk I/O

Hbo ttlen eek 'î afflle ting m any m ul tb -user s'y stem s.

Sy stem perform anee is further enhaneed by the S'rlr ts fou r fu ll-track data*

buffers. O n each disk read , an entire traek is read into one of the data buffers.

W hen subsequent seetor requests are on the sam e traek (as is likely), the data

is im m ediately available. If a11 the buffers are full w hen a new read request

appears, th e ST X either diseards or w rites back to disk the least-used of th e

four buffers (based on frequency of aceess and tim e sinz e last use).

units. T hu s, a sep arate l'drive l' ean be assig n ed to eaeh u ser, or the a pp arent

n addition, the ST X ean divide a sing le disk drive into as m any as 32 logieal

disk siz e can be m atc hed to a b aek -up m ed ium .

The ST X board is supported by the follow ing operating sy stem s: C rom ix-p lus,

@ 68000 C rom ix version 20.63 or hig her, and Z8 0 C rom ix version 11.27 or hig her.

T o run the ST IX &nd W D I-II board s coneurrently in the sam e sy stem , the W D I-II

T o o p erate th e ST X and W D I-II board s eoneurrently in the sam e sy steln, the

W D I-II m ust be m odified as dem ribed in this appendix. This procedure applies

to revisions C and D of the ST X , and revision D of the W D l-lI.

N ote : The follow ing m e ifieation sbould be done only by your loeal au th orized

C rom em eo dealerj distributor or serviee f aeility .

1. Position tlle W D I-II board w ith the solder sid e up and the edg c connec tor

tow ard s you .

2 . M lder together pins 32 and 33 of IC 42. R lder a s-ineh insulated juznper

to 1C 42 pill 33, and I'utl it through the feed-tinrough hole just above pin

33 (figure (..7-1).

3. qu rn th e board over so tn e c ofnponen t side is up utnkl the edg e e onnee tor

1. C ut tlte treces f roiu pins 32 and 33 of 1C 42 ( tk ure C - 2 ).

5. A t th e feed-through hole to the right of IC 1 Pin 7, cut th e traee going to

1C 43 pin 13 (figure C-2 ).

6. M lder the s-ineh jum per f rom the solder side to the feed-through hole at

the right of IC 1 pin 7 (figure C -2 )*

7. lnstall a 2-pin eonneetor (Cromemeo part num ber 017-0009 ) at J3, to the

1ef t of IC 1 (figure C -2 ).

8. O n th e ST IX board , install a z-p in conn ector at J 3 if it is not already in

plaée (figure 1-2 ).

9. Install th e W D I-II and ST X b oards, and eonnec t th e D M A priority eable

from the right-hand O U T pin of J 3 on the W D I-II to the right-hand IN pin

of .13 on the ST m (figures C-2 and 1-2).

This e om pletes the m Y ifieation. F ollow norm al eheckou t proe edures to verify
