None of the current CDs would boot to a point where I could get the job done. I resorted to doing it the hard way. I mounted an old 630 meg IDE hard drive (just having this around should label me a packrat) and booted the system with an eCS 2.0 RC4 CDROM. Using the eCS tools I made a compatible partition which was bootable and wrote the MBR. Next, I did a long JFS format on the partition which completed but with errors toward the end of the format process. </p></div></div></div><div class="field field-name-field-geshi field-type-geshifield field-label-above"><div class="field-label">Geshi: </div><div class="field-items"><div class="field-item even"><div class="geshifilter"><pre class="asm geshifilter-asm">eax: 0x0000aa55 43605 ecx: 0x00000000 0 edx: 0x00000080 128 ebx: 0x00000000 0 esp: 0x0000ffdc 65500 ebp: 0x00000000 0 esi: 0xffff0000 -65536 edi: 0x0008fdba 589242 eip: 0x00007c00 eflags 0x00000082 IOPL=0 id vip vif ac vm rf nt of df if tf SF zf af pf cf   cs:s=0x0000, dl=0x0000ffff, dh=0x00009b00, valid=1 ds:s=0x0000, dl=0x0000ffff, dh=0x00009300, valid=1 ss:s=0x0000, dl=0x0000ffff, dh=0x00009300, valid=7 es:s=0x0000, dl=0x0000ffff, dh=0x00009300, valid=1 fs:s=0x0000, dl=0x0000ffff, dh=0x00009300, valid=1 gs:s=0x0000, dl=0x0000ffff, dh=0x00009300, valid=1 ldtr:s=0x0000, dl=0x00000000, dh=0x00000000, valid=0 tr:s=0x0000, dl=0x00000000, dh=0x00000000, valid=0 gdtr:base=0x000faeb2, limit=0x30 idtr:base=0x00000000, limit=0x3ff</pre></div></div></div></div>
