Symptoms

• Truncation of Cylinders
• System Hangs at Post
• Cylinder Wrap
• System Hangs at Boot
• Not Receiving the Full Capacity

7
Solutions

• Use MAXlBLAST
• Upgrade the BIOS
• Use a BIOS Card
• Use FAT 32
• Use a Enhanced EIDE Controller Card

8
Hardware

• CD ROMS
• Dual Drives
• Memory
• Tape drives
• Networks

9
Jumpers

• Cylinder reduction jumper
• Master / Slave on the primary bus
• Master / Slave on the secondary bus
• Jumper numbers location can be different per
  model number. Make sure you check your
  documentation.

MaxlBlast Installation Software

• Self Booting OS
• Reads system information
• Partition copy
• No cylinder skew
• BIOS information
• LBA detection
• You can disable without losing data
• Supports FAT 32

12
MAXBlast Installation

• Boot to diskette
• Record system information
• Setup drive
• System disk
• Choose partition sizes
• Re-boot and load OS

13
DOS Windows Questions

• Why do I have to create more than one partition?
• Cluster Size
• Million Bytes VS Mega Bytes ( Why am I not
  getting the full capacity? )
• Drive to drive copy

Drive Not Recognized
Resolutions
Symptoms

• Installation errors (Verify drive is installed
  properly)
• Check Jumpers (master/slave)
• Check for Energy Management jumpers
• Check power supply cable connections
• Check ribbon cable connections
• Check for power management software
• Compatibility issues (Drive compatability can
  prevent proper communication between two drives
  on the same cable)
• Ensure Master/Slave jumpers are correct
• Verify that each drive can work alone on the
  system
• Try reversing the master slave roles
• Install the second drive on a secondary controller

• Hard Disk is not recognized or detected by the
  CMOS/BIOS program, either in the BIOS/CMOS Auto
  detect feature or in the POST.

19
Not Seeing the Full Capacity
Resolutions
Symptoms

• Installation errors (Verify drive is installed
  properly)
• Check BIOS configuration
• some BIOSs do not support larger disk drives.
  Enable LBA mode in BIOS settings
• Install the drive using MaxBlast
• Upgrade BIOS or install a BIOS controller card
  that supports large drives
• Install the cylinder limitation jumber if the
  drive is over 2.1gigs and use MaxBlast to
  install.

• General issues affecting drive capacity
• Data corruption
• cross linked files
• Problems loading O.S.
• system hangs on Boot up

20
Boot Failure
Resolutions
Symptoms

• Installation errors (Verify drive is installed
  properly)
• Check Jumpers (master/slave), cables, controller
  card seating
• Check IDE interface/controller for BIOS. Make
  sure controller BIOS is not conflicting with
  motherboard BIOS
• Check BIOS EIDE features including Block Mode,
  Multi-sector transfer, 32 bit transfer, PIO mode
  reduce to minimum value or disable
• Check AT Bus Clock speed and set between 8-10 MHZ
• Increase time for boot process to occur by
  enabling floppy seek at boot, above 1 meg mem
  test, set boot pre-delay to highest value.
• Verify that the primary DOS partition is set
  active

• Drive is recognized and properly handled during
  post but is unable to load the operating system

21
Issues Loading O.S.
Symptoms
Resolutions

• Installation issues
• Check parameters, translation mode
• verify capacity limitations, jumpers
• Check IDE interface/controller for BIOS-no
  conflicts with motherboard BIOS
• Check BIOS EIDE features including Block mode,
  multi-sector, 32 bit transfer, PIO mode reduce
  all to minimum values or disable
• AT BUS clock speed set between 8-10 MHZ
• Increase Boot up time by enabling Floppy drive
  seek at boot, above one meg mem test, and
  sequence to A, C
• Verify boot partition is primary and active in
  Fdisk
• Try replacement controller card

• Primary master hard drive is recognized and
  properly handled during post but is unable to
  load the operating system
• Failure to load the O.S. can be related to many
  different causes including installation
  configuration, communication problems, and
  hardware failures.
