Sun Ultra 5 new user
Hi

I have just acquired an Ultra 5. It has 256MB of memory and a 360Mhz Ultra IIi SPARC processor. So far, I have had some typical fun and games to get it working:
- It had a dead NVRAM chip. I hacked it open and installed a CR2032. It looks suitably bodged up, but is working. I set the MAC address and machine ID to some existing values that were on a web site (how to), because my machine is connected to a LAN and accesses the Internet via a router.
- There was no hard drive, so I slung in an old 8.2GB hard disk.
- I then installed Solaris 2.6 and configured it for DHCP. It can connect to the Internet.

So far, so good.

I have some questions though and I hope you can help.

What is the latest version of Solaris that will run comfortably on this machine? I have a copy of Solaris 10 but it will not boot (with a DVD reader installed it complains that it hasn't got enough memory). But I read that Solaris 10 on these machines is too slow.

Is the memory really limited to 512Mb? If that is true, how does the Ultra 10 (which I read uses the Ultra 5 motherboard) manage a maximum of 1Gb?

Is it "safe" to connect to the Internet? I'm thinking "vulnerabilities" here. Bear in mind it is sitting behind a firewall. I would like to be able to SSH into it from outside.

I notice it has no C compiler. What is the best approach for getting this installed, and how do I do it?

Finally, what's the best (fastest, most secure, easiest to use) Linux distribution for this and can it dual boot?

Thanks
JonB

esp

ESP(4)							   BSD Kernel Interfaces Manual 						    ESP(4)

NAME

     esp -- Qlogic FEPS and FAS366 SCSI driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device scbus
	   device esp

HARDWARE

     The esp driver provides support for the Qlogic FAS216 and FAS408 SCSI controller chips found in a wide variety of systems and peripheral
     boards.  This includes the Qlogic SCSI cards found in most Sun Ultra 1e and Ultra 2 machines.

     For Qlogic PCI SCSI host adapters, the isp(4) driver should be used in place of the esp driver.

IMPLEMENTATION NOTES

     During the boot sequence, the esp driver searches the linked list for LUN info by LUN ID.	At this point the driver will attach on that
     instance, and then attempt to attach every sub-device.

     There are at least 4 variations of the configuration 3 register.  A second config register must be loaded to inquire the chip revision, oth-
     erwise the ncr53c9x_reset() function will not set the defaults correctly.

     The drive attach routine attempts to set the appropriate bit to put the chip into Fast SCSI mode so that it does not have to be figured out
     each time.  This will then be stored in the NCR registers for later use.

     The esp driver makes use of the LSI 64854 DMA engine which contains three independent channels designed to interface with an NCR539X SCSI
     controller; an AM7990 Ethernet controller; and certain types of parallel port hardware.  As such this driver may eventually replace the
     amd(4) driver for network hardware.

DIAGNOSTICS

     The following driver specific error messages may be reported:

     esp: cannot map %d segments  The device was unable to map segments while mapping the SCSI devices in DMA mode.

     unknown variant %d, devices not attached  An unknown version of the card was found and devices will not be attached.

     Unhandled function code %d  The device returned a function code which the driver is unable to handle, most likely during negotiation.

     esp:%d:%d: selection failed %d left in FIFO  The target left the command phase prematurely.  If a command did not reach the device then it
     will be reported as shown above.

     invalid state: %d	The device has reached an invalid state.

HISTORY

     The esp driver was written for NetBSD by Eric S. Hvozda.  The esp driver was then ported to FreeBSD 5.3 by Scott Long <scottl@FreeBSD.org>.

AUTHORS

     This manual page was written by Tom Rhodes <trhodes@FreeBSD.org> instead of porting the original from NetBSD.

BUGS

     The esp driver includes the sbus front-end but lacks the PCI front-end.  Thus it can only support the FEPS/FAS366 SCSI found in Sun Ultra 1e
     and Ultra 2 machines at this time.

     This driver should eventually replace the amd(4) driver, but that requires porting the PCI front-end mentioned above.
