I told my mate who's got a hardware problem that you guys are the best at sorting them out, here's his text:
Setup: AWARD BIOS 2.1, PIO set to 'AUTO'. UDMA enabled for all channels, AUTO enabled for all drive configurations, i.e no user configuration.
Gigabyte motherboard, GA-6BA with 440BX AGP chipset, 100Mhz FSB, 350-Mhz Pent2.
Primary IDE Master - 8.4Gb Western Digital Caviar, UDMA/33 supported
Primary IDE Slave - 13Gb Maxtor, UDMA/33 supported
Secondary IDE Master - 4.3Gb Samsung with UDMA/33 support, running Linux
Secondary IDE Slave - Hitachi 2500 DVD
128Mb Cube RAM,
Windows98 retail (not SE), defaults on installation to Intel BusMaster driver:
Problem:
The DMA check boxes for Primary Master and Primary Slave are unchecked, although both support DMA and UDMA. The DMA checkbox is checked for the Secondary Master, however. After checking DMA for all drives then rebooting, it defaults back to unchecked for the Primary master and slave.
Is there a valid hardware reason why this is happening.?
I understand there can be an 8.4Gb limit, and if a drive exceeds this, and is not the primary device, i.e the one from which boot occurs, then there are DMA issues. Not sure if this is crap or not...
