NEC RISCstation's ARC-BIOS maps it's video memory (physical address
0x40000000) at virutal address 0xeb000000.
(Winmsd and ARC-BIOS reports that it's system type is "Microsoft-Jazz")

But, ...

It seems that NEC riscserver is different from riscstation... ?

BTW, RISCstation now works in multi-user mode, and I'm going to
send patch to pefo, and merge OpenBSD's changes to NetBSD...
(But not yet finished...)
