I turned the cache on and ran for a while, without any serious problems. With the cache on or off, I have problems unpacking the compressed tar archives of the distribution. I get errors part way through. Here's what dmesg says, by the way: CPU: 78-MHz Pentium 735\\90 or 815\\100 (Pentium-class CPU) Origin = "GenuineIntel" Id = 0x524 Stepping=4 Features=0x1bf<FPU,VME,PSE,MCE,CX8,APIC> real memory = 16384000 (4000 pages) avail memory = 15085568 (3683 pages) Probing for devices on the ISA bus: sc0 at 0x60-0x6f irq 1 on motherboard sc0: VGA color <8 virtual consoles, flags=0x0> lpt0 at 0x378-0x37f irq 7 on isa lpt0: Interrupt-driven port lp0: TCP/IP capable interface psm0 at 0x60-0x63 irq 12 on motherboard sio0 at 0x3f8-0x3ff irq 4 on isa sio0: type 16550A sio1 at 0x2f8-0x2ff irq 3 on isa sio1: type 16550A pca0 on motherboard pca0: PC speaker audio driver bt0: Bt946C/ 0-PCI/EISA/VLB(32bit) bus bt0: reading board settings, busmastering, int=15 bt0: version 4.24, sync, parity, 32 mbxs, 32 ccbs bt0: targ 0 sync rate=10.00MB/s(100ns), offset=15 bt0: targ 3 sync rate= 5.00MB/s(200ns), offset=08 bt0: targ 6 sync rate= 4.54MB/s(220ns), offset=15 bt0: Enabling Round robin scheme bt0 at 0x330 irq 15 on isa (bt0:0:0): "CONNER CFP1060S 1.05GB 2035" type 0 fixed SCSI 2 sd0(bt0:0:0): Direct-Access 1013MB (2074880 512 byte sectors) sd0(bt0:0:0): with 2756 cyls, 8 heads, and an average 94 sectors/track (bt0:3:0): "HP HP35470A 1109" type 1 removable SCSI 2 st0(bt0:3:0): Sequential-Access density code 0x13, variable blocks, write-enabled (bt0:6:0): "PLEXTOR CD-ROM PX-4XCS 1.01" type 5 removable SCSI 2 cd0(bt0:6:0): CD-ROM cd0(bt0:6:0): NOT READY asc:3a,0 Medium not present can't get the size wdc0 at 0x1f0-0x1f7 irq 14 flags 0xff8004 on isa wdc0: unit 0 (wd0): <Conner Peripherals 545MB - CP30544>, multi-block-4 wd0: 520MB (1065456 sectors), 1057 cyls, 16 heads, 63 S/T, 512 B/S wdc0 not probed due to I/O address conflict with wdc0 at 0x1f0 fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa fdc0: NEC 72065B fd0: 1.44MB 3.5in 1 3C5x9 board(s) on ISA found at 0x300 ep0 at 0x300-0x30f irq 1 on isa ep0: aui/bnc/utp[*UTP*] address 00:20:af:a1:d2:a6 irq 1 npx0 on motherboard npx0: INT 16 interface Probing for devices on the pci0 bus: configuration mode 2 allows 16 devices. chip0 <Intel 82434LX PCI cache memory controller> rev 17 on pci0:0 CPU: Pentium, 100MHz, CPU->Memory posting ON Cache: None3-2-2-2/4-2-2-2 DRAM: page mode memory clocks=X-4-4-4 (70ns) CPU->PCI: posting ON, burst mode ON, PCI clocks=2-1-1-1 PCI->Memory: posting ON chip1 <Intel 82378IB PCI-ISA bridge> rev 3 on pci0:2 [40] 40420 [50] 0 [54] 4000000 pci0:3: vendor=0x1095, device=0x640, class=storage [not supported] pci0:13: vendor=0x104b, device=0x1040, class=storage [not supported] map(10): io(fcfc) vga0 <VGA-compatible display device> rev 0 int a irq 9 on pci0:14 mapreg[10] type=0 addr=40000000 size=800000. pci0: uses 8388608 bytes of memory from 40000000 upto 407fffff.

You've done an incredible job under enormous pressure. ------------------------------------------------------------------ Danny J. Zerkel Photon Farmers "Cultivating Your Digital Image"
