Topics covered within this document include: General Information Test Information Additional Troubleshooting Information **************************************************************************** * GENERAL INFORMATION * **************************************************************************** The PIIX Bus Master IDE Driver for IBM OS/2 should ONLY be used with versions 2.x or Warp* 3.x of the IBM OS/2 operating system (Production Versions). The driver included in this package is intended for use on Pentium(tm) processor based 82430FX platforms ONLY. The driver will auto-identify all the devices connected to the PIIX IDE interface. Depending on the capabilities of the devices connected to the system, the driver will initialize the PIIX IDE interface for bus mastering operation. Only devices identified as bus master capable (refer to the README.TXT) will be accessed as a bus master; all other devices (including all ATAPI CD-ROM drives) will be accessed in a PIO-only fashion. ATAPI CD-ROM drives are handled by the standard filter driver that comes with OS/2, or is supplied by the device vendor, and runs in standard PIO mode. Future releases of the PIIX Bus Master IDE driver will allow ATAPI CD-ROM drives identified as bus master capable to be used as a bus master. ATAPI tape drives have not been tested with this driver and are not supported in the current release of this driver. Proper setting of the ISA speed switch/jumper is required by the driver. Incorrect settings can result in unreliable system operation. The proper settings are as follows: 1. For 90 MHz and above processor speeds (PCI Clock Frequency is 30/33 MHz), set the ISA speed switch/jumper to 1/4 speed (slow) [PCI Clock Frequency/4]. 2. For a 75 MHz processor speed (PCI Clock Frequency is 25 MHz), set the ISA speed switch/jumper to 1/3 speed (fast) [PCI Clock Frequency/3]. **************************************************************************** * TEST INFORMATION * **************************************************************************** For any of the items in the lists below followed by this plus sign (+), refer to the ADDITIONAL TROUBLESHOOTING INFORMATION section for more detailed information. The following fixed disk drives were tested with the PIIX Bus Master IDE Driver: Conner*: CFA540A CFA850A CFA1080A CFS425A + CFS1275A IBM*: DALA-3540 DALA-31080 Maxtor*: 7213AT 7540AV + 7245AV + 7850AV + 71260AT + 71626AP + Quantum*: FB540A FB1080A LPS270A TRB850A Seagate*: ST5660A ST5850A ST51080A Western Digital*: AC2420 AC2850 AC31000 AC31600 AC21000 The following ATAPI CD-ROM drives were tested with the PIIX Bus Master IDE Driver: Gallant*: GCD-R542B IBM FX400*: CRMC-FX400C2 Mitsumi*: FX400 NEC*: CDR260R CDR271 CDR272 CDR273 Sony*: CDU55E CDU78E TEAC*: DC5-E6 Torisan*: S1G C3G Toshiba*: XM-505302B Wearnes*: CDD-120 CDD-220 **************************************************************************** * ADDITIONAL TROUBLESHOOTING INFORMATION * **************************************************************************** Verifying the installation of the driver and other generic troubleshooting is discussed in the README.TXT file contained within this package. This section describes additional issues that are not currently described in the README.TXT file. If any of the following problems are encountered, the driver should be un-installed following the instructions outlined in the README.TXT file. This section contains more information regarding specific hardware configurations marked by a plus sign (+) in the TEST INFORMATION section of this document. Issue: The system does not operate reliably or fails to boot when the driver is installed. Solution: Un-install the driver. Issue: The driver does not support the following fixed disk drives: Maxtor 7245AV Maxtor 71626AP Maxtor 71260AT Solution: Do not install the driver in configurations equipped with these fixed disk drives. Issue: The driver does not support Quantum Maverick drives in DMA mode. Solution: Force the drive into PIO-mode operation by using PIIXIDE.ADD command line parameters in the CONFIG.SYS. For example, if this drive is set up as a slave on the primary cable, the following command line should be used to load the driver: BASEDEV=PIIXIDE.ADD /A:0 /U:1 /!BM NOTE: For a description of the command line parameters see the README.TXT file. Issue: The driver does not support Maxtor 7850AV and 7840AV drives with the multi-sector option enabled. Solution: Turn off the multi-sector feature using PIIXIDE.ADD command line parameters in the CONFIG.SYS. For example, if the drive is the master on the secondary cable, the following command line should be used: BASEDEV=PIIXIDE.ADD /A:1 /U:0 /!SMS NOTE: For a description of the command line parameters see the README.TXT file. Issue: The driver does not support the Conner CFS425A drive in DMA mode. Solution: Force the drive into PIO-mode operation by using PIIXIDE.ADD command line parameters in the CONFIG.SYS. For example, if this drive is set up as a slave on the primary cable, the following command line should be used to load the driver: BASEDEV=PIIXIDE.ADD /A:0 /U:1 /!BM NOTE: For a description of the command line parameters see the README.TXT file. **************************************************************************** Intel is making no claims of usability, efficacy or warranty.
