+ The Bt445S and Bt747 controllers can cause problems when ISA DMA
+ is selected as an option. With the EISA controller the remedy is
+ easy - simply turn it off using your EISA configuration utility.
+ With the Bt445S, which is a VLB card, you must switch the undocumented
+ "SW10" on "SB2" to the off position. Also note that certain revisions
+ of the Buslogic firmware can cause data corruption with systems
+ containing more than 16Mb of memory. If you find this to be the case,
+ temporarily remove your extra memory and contact Buslogic for an
+ upgrade.
