I have an AST Bravo MS 5166 that is perpetually under construction. It has an Intel Advanced/RH motherboard with an AST bios. My problem is that even though I disable the parallel and serial ports, as well as disabling the on board sound, Win95/98 will always detect those items. I've tried a number …

Just got a Vectra VA6/200 and would like to remove the rear plastic as it’s cracked and filthy. However, the lock is keeping the rear panel on. Does anyone have a good way of removing the lock so I can take the plastic off? Also, don’t have a key. The lock is already in the unlocked position as I …

Jumpers are set to 1 MB, but the cache chips are 256 x 1 each, so 256 kb in total. Isn't there a hardware summary screen when the system boots? What does it say? I changed the jumpers to reflect 256 cache. The hardware summary screen at boot mentions nothing of the cache. That cache looks bona-fide …

Hi all, It seems cache is still the bane of my existence. I have a CH-890C motherboard and despite being over 20 years old, the Dallas Clock Chip is still ticking. But after running a number of dos benchmarking programs, I can't get any read on how much cache I have on board. I'm hoping that someone …

I didn't give up! :-) I have spent way too much money in my pursuit of going down the LPX route. I've put together and refurbished a Packard Bell 386 and 486. I refurbished a Zenith Data Systems Pentium 90 desktop. I made a very big mistake and tried to refurbish a AST desktop. That didn't work out …

Awesome machine! Good call on the CX450M. I've been using one on my test desk and it's so quiet you wouldn't even think it's on. I've been throwing around the idea of a P3 build with the same mobo you used, but I'd really like the ability to use my ISA peripherals. That leads me to either a P3V133 …

I think that you'll want the 2 rows of pins towards the riser card empty. Thanks, I appreciate the help. To be honest, in my 30 some years of computing, I've never tried to install cache, so even this is new for me. If you look at the link Roman555 provided, it shows how, when, where, etc. the …

I just acquired a HP P920 Flatscreen CRT, which means I'm now required to get an HP computer to go with it. So I'm going to be leaning towards a HP Vectra VL5 Series 5. My issue is that since HP has purged their site of anything Vectra related, I can't just download everything I would have needed …

Mine has a riser card that's ISA only unfortunately. I'd like to get one that has ISA and PCI (don't know if there's both, or just one or the other) to install a PCI video card. Do you know what graphics chipset you have? That and a photo of the motherboard would go a long way. The only Packard …

Does that also depend on the style connector on the motherboard as well? The motherboard in mine looks like VLB slots. Also, where does one simply find riser cards for certain systems? This is a Packard Bell 450 motherboard. pb450.jpg The riser card slot is split between two slots. This is pretty …

But yeah the riser cards should be swappable as long as it's the same height. Almost all of the ISA riser cards have the same interface. The only only one that has a different interface is the PB450, also known as the "Firehawk." The 450's interface is split between two ports as apposed to the …

Nothing stupid as there can be trial and error Very true. At any rate, I bit the bullet and purchased a lot of 11 of these... 20ns.jpg They're 20ns so it fits the profile. PB wanted you to have 15, 20, or 25ns for cache. I'm also going to get a 10 count of 32kx8 15ns cache. It will only give me …

As far as I understand it, tag SRAM chips are just SRAM chips If Tag SRAM chips are the same thing as cache chips, then could I take 5 MT5C1008 (SRAM, 128K x8 DIP32) chips and put them in all 5 cache slots. I wouldn't have to worry about only installing 4 MT5C1008 (SRAM) along with a separate …

I'm adding a Packard Bell 486 to my collection, and I want to add cache to the motherboard.

I wanted to add 512k of cache but I'm having a difficult time finding the proper chips to …
