+ * 10 Apr 1998 (Good Friday) - Received EN144302 by email from Iomega.
+ * Scarry thing is the level of support from one of their managers.
+ * The onus is now on us (the developers) to shut up and start coding.
+ *                                              11Apr98 [ 0.10 ]

+ *
+ * It manages to find the drive which is a good start. Writing data during
+ * data phase is known to be broken (due to requirements of two byte writes).
+ * Removing "Phase" debug messages.
+ *
+ * PS: Took four hours of coding after I bought a drive.
+ *      ANZAC Day (Aus "War Veterans Holiday")  25Apr98 [ 0.14 ]
+ *
+ * Ten minutes later after a few fixes.... (LITERALLY!!!)
+ * Have mounted disk, copied file, dismounted disk, remount disk, diff file
+ *                    -----  It actually works!!! -----
+ *                                              25Apr98 [ 0.15 ]
+ *
+ * Twenty minutes of mucking around, rearanged the IEEE negotiate mechanism.
+ * Now have byte mode working (only EPP and ECP to go now... :=)
+ *                                              26Apr98 [ 0.16 ]
+ *
+ * Thirty minutes of further coding results in EPP working on my machine.
+ *                                              27Apr98 [ 0.17 ]
+ *
+ * Due to work commitments and inability to get a "true" ECP mode functioning
+ * I have decided to code the parport support into imm.
+ *                                              09Jun98 [ 0.18 ]
+ *
+ * Driver is now out of beta testing.
+ * Support for parport has been added.
+ * Now distributed with the ppa driver.
+ *                                              12Jun98 [ 2.00 ]
+ *
+ * Err.. It appears that imm-2.00 was broken....
+ *                                              18Jun98 [ 2.01 ]
+ *
+ * Patch applied to sync this against the Linux 2.1.x kernel code
+ * Included qboot_zip.sh
+ *                                              21Jun98 [ 2.02 ]
+ *
+ * Other clean ups include the follow changes:
+ *    CONFIG_SCSI_PPA_HAVE_PEDANTIC => CONFIG_SCSI_IZIP_EPP16
+ *    added CONFIG_SCSI_IZIP_SLOW_CTR option
+ *                                                      [2.03]
+ *  Fix kernel panic on scsi timeout.		20Aug00 [2.04]
+ *
+ *  Avoid io_request_lock problems.
