You are stuck with the 16Mb limit without a patch.
All the pieces are there for you to do a 32-bit driver
(pci code in the updates, fileserver scsi4201 driver).

Hello everyone!

I have a single question:

	I use a Buslogic 946C SCSI-Controler in my Plan9 PC, what means that the
	AHA1542 emulation is used. Does this also mean, that the driver can only
        address the lower 16 MBytes RAM (without the driver patch), or is it
	possible to ignore this ISA limit on my PCI system?

Thank you for any answers.

Regards,

	Henner
