but here's a funky problem i ran into - when i tried to add a slave, no hard drive is found. doesn't matter if i use the 4 gig or the 80 gig as the master. this might be due to the bios issue tho.
Your BIOS can only see 4GB MAX, new BIOS or not.
Old systems / MoBo's CPU's etc are NOT supported, everything has to end, and in IT, the end is quicker than most

There is a VERY good chance that your 'Latest' BIOS is still pre-massive GB HDD's. [over 4GB]

My first serious system was a 486 DX2 66 MHz CPU with 300MB HDD and 16 MB of RAM, running Windows 3.11.
It was a work unit, the PPA to the MD had used it, so we're talking the dogs bollox of systems too

And that was in 1995 .............TEN YEARS
