Hello,
I have more infos about my problem booting my DecServer 3100.
I've made a ecoff kernel (using elf2ecoff), so i can use exactly the same
hardware as under Ultrix (wich work fine under ultrix).
I've got a kernel with DEBUG defined in sii.c, and sii_debug = 9. This
appear to be a scsi problem.
I've got two Micropolis 600 Mo at scsi 0 and 1, and a rz23 ant scsi3.

At boot, i get a lot of debug output, ending with:
#sii_CmdDone: rz target 0 cmd 3 err 0 resid 14
#sii_StartCmd: rz taget 0 cmd 0x0 addr 0
#
#sii_StartCmd DONE ds1004
#
#sii_StartCmd DONE ds1004

And then the kernel hangs
If i remove my two Micropolis, i only get (with or without external scsi
terminator)
#Beginning old-style SCSI device autoconfiguration
#sii_StartCmd: rz target 0 cmd 0x12 addr ffffeab8 size 1068 dma 1
and then it hangs. 

This station has 24Mb ram installed, if this matters.
Any idea ?
