- * From: andy@cercle.cts.com (Dyan Wile)
- *
- * Below is a patch for DTC-2278 - alike software-programmable controllers
- * The code enables the secondary IDE controller and the PIO4 (3?) timings on
- * the primary (EIDE). You may probably have to enable the 32-bit support to
- * get the full speed. You better get the disk interrupts disabled ( hdparm -u0
- * /dev/hd.. ) for the drives connected to the EIDE interface. (I get my
- * filesystem  corrupted with -u1, but under heavy disk load only :-)
- *
- * This card is now forced to use the "serialize" feature,
- * and irq-unmasking is disallowed.  If io_32bit is enabled,
- * it must be done for BOTH drives on each interface.
- *
- * This code was written for the DTC2278E, but might work with any of these:
- *
- * DTC2278S has only a single IDE interface.
- * DTC2278D has two IDE interfaces and is otherwise identical to the S version.
- * DTC2278E also has serial ports and a printer port
- * DTC2278EB: has onboard BIOS, and "works like a charm" -- Kent Bradford <kent@theory.caltech.edu>
- *
- * There may be a fourth controller type. The S and D versions use the
- * Winbond chip, and I think the E version does also.
- *
