UDMA tips and tricks under NetWare - screenshots section

 NetWare 4.11 on an 'Intel BLKD875PBZLK "Bonanza" Dual channel DDR400/333 w/ECC' board based, 3.0GHz, 1GB RAM, 2*120GB IDE system.

ATA configuration possibilities. Legacy can be the working solution.

        



"Enhanced" setting of ATA/IDE configuration in the BIOS resulted in strange behavior and NetWare couldn't see the drives. [detailed console log]

Setting ATA/IDE configuration in the BIOS to "Legacy" helped. Even then, I had to use the /legacy switch for ideata.ham. [detailed console log]
