CONFIG_SCSI_IZIP_SLOW_CTR: ppa/imm option - Assume slow parport control register

General informations

The Linux kernel configuration item CONFIG_SCSI_IZIP_SLOW_CTR:

Help text

Some parallel ports are known to have excessive delays between changing the parallel port control register and good data being available on the parallel port data/status register. This option forces a small delay (1.0 usec to be exact) after changing the control register to let things settle out. Enabling this option may result in a big drop in performance but some very old parallel ports (found in 386 vintage machines) will not work properly.

Generally, saying N is fine.
