This driver hasn't seen any recent bug fixing and is one of the last
drivers using the scsi_module.c infrastruture that has been deprecated
15 years ago.

- This driver supports all EATA-PIO protocol compliant SCSI Host
- Adapters like the DPT PM2001 and the PM2012A. EATA-DMA compliant
- host adapters could also use this driver but are discouraged from
- doing so, since this driver only supports hard disks and lacks
- numerous features. You might want to have a look at the SCSI-HOWTO,
- available from <http://www.tldp.org/docs.html#howto>.
