I am running Win98, Win3.11 and NT4 Server on a Jet motherboard with a LX chipset and a P2 233mhz processor. BIOS is Award v4.51. I have a Graphics Blaster 4mb graphics card, a Linksys 100base TX NIC, and an Adaptec 2940AU SCSI card in the PCI slots. I've used Partition Magic to create a Boot Partition to choose between Win311 and Win98/NT4.
The problem is that when I boot, I get a 'Host Configuration error' and then 'SCSI Bios not installed'. This only happens when the PC has been cold booted and then re-booted a few times. After about 15 minutes of warming up, I reboot with Ctr-Alt-Del and everything is OK. ID numbers are assigned to the SCSI drives and the Adaptec BIOS installs as normal.
I've tried swapping the cards around in the PCI slots, and changing settings in the BIOS but the problem still persists. The problem only started when I installed the NIC.
Has anyone got any ideas about this, because it is very annoying, especially when I have to reboot to different operating systems and the configuration crops up intermittently at each reboot.
