Does this solve the problem for all cases?
I have noted that Award Bios based mainboards do not load the add-on bios;
however, most AMI based mainboards do this correctly.
The force enable was based on a general concern that off-board chipsets
are depended on the ROMS for features.
The reason for stroking the rom is to force it on.
Since the Promise card in all releases (Ultra/Defender/FastTrak)
all require that the rom be enabled, or the (U)DMA will not be enabled by
default. Note that FastTrak with always have its bios enabled by default.
I am currently working on making the FastTrak become automatic RAID 1.
I have two booting successful RAID 1 Mirror systems up now,
but here is the catch:
There is something the config space to be stroked/set that the "UltraTune"
utility does, or in the "hwif->dma_extra" 16 ioports beyond the busmaster
base.
