Problems booting with Tyan NCR825 scsi

Problems booting with Tyan NCR825 scsi

I recently purchased a Tyan Titan III with the Tyan Yorktown Fast-Wide SCSI
controller.  When I boot to MSDOS from Win95 and use loadlin to run Linux,
I experience the following error:

scsi-ncr53c7,8xx: NCR53c825 at memory 0xf4000000,io 0x6000,irq 12
scsi0: using io mapped access

This may be related to the fact that I am also having problems with my
system locking up when I load Win95 with the NCR825 32 bit driver.  The
system runs fine when I boot directly into Linux (the scsi tests complete
successfully) and I can run Win95 using the real mode drivers.

My system configuration is as follows:
Tyan Titan III w/ 16MB EDO RAM, 256K PB cache
Tyan S1365 Fast-Wide PCI SCSI controller
Diamond Stealth Video 2001 PCI with 2MB DRAM
PAS-16 Audio Card
Supra 28.8 PNP Modem
2 SCSI Hard Drives (ID 4&5), 1 SCSI CDROM (ID 0), 1 SCSI Tape Drive (ID 1)

If anyone has any ideas what might be wrong, please send me an e-mail.
