| MISCELLANEOUS TECHNICAL NOTES |
|------------------------------------------------------------|
| The DMS2000-M1 has no jumpers to configure. This |
| controller is compatible with the Western Digital |
| WD1003-WA2. One minor incompatibility exists between these |
| two controllers. If the hard drive contains more than |
| eight heads, the WD1003-WA2 numbers heads 8 through 15 as |
| 0 through 7 in the medias ID fields. The DMS2000-M1 |
| controller numbers heads 8 through 15 as 8 through 15. You |
| must reformat the hard disk if you are replacing a |
| WD1003-WA2 due to this incompatibility. |
| |
| This problem is not manifested in drives with less than |
| eight heads. |
