We have two Compaq boxes (OK, it wasn't my idea to } buy those so please no flames ;). One 486DX4/100 ISA/PCI, another Pentium 90 } EISA/PCI. The Pentium one comes with integrated PCI SCSI compatible with } itself and a Netflex Ethernet, also compatible with itself. The 4/100 box } have an on-board PCI Cyrus Logic video board. } } All of these may look very exiting, but also I have two AHA-2940 PCI SCSI } host adapter and some fast SCSI disks that I want to use for FreeBSD 2.1. The } problem is as follows : } } When inserted in the 4/100 box, the 2940 is claiming that it detects the disks } and installs the bios. If the disk have a DOS partition, it will boot with } no problems, and show ~2Mb/s transfer rates. The same aplies to the P90 box } (if the on-board SCSI is switched off with ECU). But the FreeBSD 2.1'w floppy } kernel won't detect the adapter on both machines. } } } I took a look in the kernel code, but lacking PCI programming expirience, it's } a hell of a job to understand why it's not working.
