  *
  * This is the IDE probe module, as evolved from hd.c and ide.c.
  *
- * Version 1.00                move drive probing code from ide.c to ide-probe.c
- * Version 1.01                fix compilation problem for m68k
- * Version 1.02                increase WAIT_PIDENTIFY to avoid CD-ROM locking at boot
- *                      by Andrea Arcangeli
- * Version 1.03                fix for (hwif->chipset == ide_4drives)
- * Version 1.04                fixed buggy treatments of known flash memory cards
- *
- * Version 1.05                fix for (hwif->chipset == ide_pdc4030)
- *                     added ide6/7/8/9
- *                     allowed for secondary flash card to be detectable
- *                      with new flag : drive->ata_flash : 1;
- * Version 1.06                stream line request queue and prep for cascade project.
- * Version 1.07                max_sect <= 255; slower disks would get behind and
- *                     then fall over when they get to 256.    Paul G.
- * Version 1.10                Update set for new IDE. drive->id is now always
- *                     valid after probe time even with noprobe
+ * -- increase WAIT_PIDENTIFY to avoid CD-ROM locking at boot
