Changes:

  • BIOSDRVS builds again (broken since r609). Also removed the last remnants of RESERVE_DIAGNOSTIC_CYLINDER from BIOSDRVS that I missed in r606.
  • Put in a limit on the P-CHS cylinder count in an attempt to improve compatibility with some CF cards that violates the ATA specification. The limit applies only to the BIOS. BIOSDRVS will continue to show the true cylinder count since we might want to add code later to warn the user when encountering incompatible drives like these.
  • Optimized the bug fix in r611.
  • Updated the copyright notices in XTIDECFG and BIOSDRVS.
