Hi,

I was given an old Presario 7478 in pieces, and put it back together again. The memory, CMOS battery, hard drive, and PC cards were gone, the jumpers were wrong, and the K6-2/533 processor didn't seem healthy (had been jumpered for 2.8V), so I rebuilt it with a known good K6-2/550, an available 64MB PC133 SDRAM, 6.3GB ATA-33 WD and the original PHILLIPS CDD4401/71 CD-Drive. I set the jumpers for 2.2V CPU, 100MHz FSB, and 5.5 multiplier. It has a Camaro board which I understand is actually a Mitac 5114vu, except with three SDRAM slots. I downloaded the manuals from both manufacturers and see the chip set is the MVP4 Apollo, the successor to my FIC VA-503+ MVP3 which runs WinXP just fine.

(I'm using an IOGear MiniView 4-port KVM with the Compaq and if it's selected during Win98SE boot, the mouse isn't detected. The other three PC's on the switch have no problem - they are running WinXP.)

According to Mitac the outside IDE port is the secondary, whereas Compaq says it's the primary. (I get the impression Compaq screwed around with the BIOS to make the board both abnormal and unique.)

I went with Mitac and placed both hard drive (master) and CD-Drive (slave) on the inside port (reports as drives 1 and 2 -- Mitac must be right). Win 98SE installs and runs fine. However, when I try to install WinXP, after it finishes going through the motions of formatting the drive (either FAT32 or NTFS) it reports it was unable to do so and says the drive is probably defective (it isn't). It did this regardless of which IDE port I tried. I finally tried first formating FAT32 via a Win98 start diskette and then skipping the WinXP format in Setup, that worked.

At the initial Windows boot during WinXP install, the KVM mouse was again missed (again with console selected) but install proceeded pretty much without incident from there (seemed like the CD-Drive may have timed out two or three times -- had to power the PC down and up at displayed "19 minutes remaining" to recover from what appeared to be a permanent stall.)

1) I'm wondering if it's possible to install a Mitac BIOS in the board and get away from the Compaq encapsulation -- turn it back into a normal mainboard.

2) I'm also wondering why WinXP setup can't format the hard drive, whereas it can install the operating system, and whereas Win98SE can do both.

3) I'm further wondering why the mouse isn't detected when selected by the KVM console during Win98SE boot (and the initial WinXP boot during install).

4) I'm additionally wondering about the seemingly very occasional CD-Drive timeouts --a behavior I never saw during Win98SE install.

5) I'm finally wondering when my new 128MB PC133 SDRAM and LAN card are going to arrive so that it can become a "real" computer (Chuckle, chuckle!) :)

Fortunately, the KVM console mouse IS detected properly during a normal WinXP boot (unlike during a Win98SE boot) and the install did eventually complete successfully (I think -- time will tell).

Any ideas on my four items ??? Thanks -- Trevor

Another problem -- serious!

I just installed a D-Link DFE-530TX+ 10/100 LAN card in the Compaq 7478 Camaro board. The initial boot was OK, the card was detected and I installed the driver, but then I shut down and connected a LAN cable, after which WinXP fails to boot -- hangs with the white arrow on the black screen prior to the main window opening. Every effort to actually create a physical LAN connection so far has resulted in WinXP hang at that point.

What did those people DO, at Compaq? What is the correction?

Anybody out there? -- Trevor

Compaq Presario Desktop PCs - Can I upgrade my Windows 95, 98 or Me Operating System to Microsoft Windows XP? (http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&cc=us&docname=c00007685&product=94494&dlc=en&lang=en)

I understand you have changed a lot of stuff around, but you might want to check out the original Presario 7478 - Technical specifications (http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c00034134&locale=en_US&taskId=101&prodSeriesId=96411&prodTypeId=12454)

Sorry I can't help you more.

Hello,

Thanks for getting back to me. I actually did review both the Compaq Presario 7478 Tech and Mitac 5114vu manuals -- that's how I was able to get as far as I did. :) I finally worked through my installation problems excepting the Compaq BIOS apparently won't allow installation and boot from an NTSF partition. As long as I stick with a FAT32 partition I can make it work.

WinXP/SV2 has been running fine for several weeks now (with LAN), but I find the memory performance on the Compaq Camaro (Mitac 5114vu) MPV4 board to be poor at Sandra 131MB/s versus 189MB/s with the same cpu, DIMMs, and clock settings on my FIC VA-503+ MPV3 board. Since the K6-III+ mobile has a 256KB full speed internal L2 cache, the Mitac's 512KB external L2 cache versus the FIC's 1MB shouldn't make that much of a difference.

I tried bumping the Compaq BIOS to the mid 2000 version (about 7 months newer than the original), but it made no difference. In order to get access to the memory parameters (given Compaq hides virtually everything), I installed Mitac 5114vu BIOS Award v6.00PG (11/07/2001), BIOS ID 11/07/2001-VP4-686A-6A5LHM3CC-00. Unfortunately, the memory performance has actually further declined to 115MB/s.

I currently only have DIMMs installed in the first two slots (farthest from the board edge) since the third slot seems to be an add on (not even the Compaq BIOS would boot with memory only in that slot) and the original Mitac 5114vu only had two slots total. The DIMM SPD timings are PC100 2.0,2,2,5 and PC133 3.0,3,3,6 (Cpu-Z) and I'm running a 100MHz host clock.

At this point, I would retry the latest Compaq BIOS, but I've discovered the Award Flash utility refuses to install a non-Award BIOS, and the Compaq BIOS ROMPAQ refuses to replace a non-Compaq BIOS -- I'm caught both ways.

I would very much appreciate ideas on both what can be done to optimize memory performance on a Mitac 5114vu (including any configuration issues associated with three Vs two slots), and also regarding a way to reinstall the Compaq BIOS over the Award. Both would be useful :)

Thanks very much in advance -- Trevor
