7800 os/2 issues

Known Issues

  • This version of the Adaptec 7800 Family Manager Set driver added a new switch named /!PCIHW which enables the driver to skip accessing the PCI hardware registers directly, and use PCI BIOS instead. This switch could be useful for users having problems loading the driver included with OS/2 Warp or Server. Modify the CONFIG.SYS file to include the following line: 
       
		For Ultra2SCSI host adapters: 
		BASEDEV=AIC78U2.ADD /!PCIHW 
		For UltraSCSI or earlier host adapters: 
		BASEDEV=AIC7870.ADD /!PCIHW
  • Intel Errata #8511 lists known data integrity issues with the processor cache on the Saturn-1 chipset (82424TX). For this reason, Adaptec recommends that processor cache be disabled via the CMOS setup to avoid data corruption.
    For more information, see Intel Errata #8511. You may get this from Intel's FaxBack system at 800.628.2283 or 916.356.3105.
  • There are installation problems when installing on the maximum hard disk drive partition size supported by OS/2 v3.0. On OS/2 v3.0 it is a known problem. Refer to IBM for further info. IBM's APARs PJ15988 and PJ 6151 deal with this issue.
  • There are known installation problems installing OS/2 Warp v4.0 on a Micron (LSI chipset) 64 bit PCI system.
  • There are known installation problems installing OS/2 Warp with 8MB of RAM unless all the third-party basedev statements are removed from config.sys.
  • There are known installation problems installing OS/2 using two SCSI host adapters on Marl mother board.
  • Whenever you have a LVD HDD on one Ultra2SCSI host adapter and a HDD, CD-ROM, and removable Syjet on another UltraSCSI host adapter, Syjet conflicts with the CD-ROM and the system is unable to access the CD-ROM.
