- * This driver works marginally on an Emulex SC-11B controller with rev
- * level J microcode, defining:
- * int olducode = 1;
- * to force CPU stalling delays.
- *
- * It has worked with no delays and no problems on a prototype
- * SC-21 controller. Emulex intends to upgrade all SC-11s on VAXes to SC-21s.
- * You should get a SC-21 to replace any SC-11 on a VAX.
